（1）地下水分类按地下水的含水介质、赋存条件、水理性质及水力特征，勘察区地下水可分为第四系松散岩类孔隙潜水、第四系松散岩类孔隙承压水和基岩裂隙水三大类。a.第四系松散岩类孔隙潜水场区浅部地下水属第四系松散岩类孔隙潜水，分布于平原区浅部的冲海积层粉土、粉砂层中，厚度约12.60~23.00m。受大气降水和地表水补给，迳流速度缓慢，以蒸发方式和向附近河塘侧向迳流排泄为主，水位随气候动态变化明显，水位年变幅约1.5~2.0m。勘察阶段间地下水水位埋深在0.80~4.20m，水位标高在2.85~6.76m。b.第四系松散岩类孔隙承压水松散岩类孔隙承压水主要分布于上更新统冲洪积、冲积粉细砂、圆砾、卵石层中，顶板埋深27.3~37.6m左右，总厚度20.1～34.4m。实测水位埋深11.0m左右，绝对标高-4.47m。富水性好，单井涌水量1000～3000m3/d。对钻孔灌注桩施工有一定影响，施工时应引起重视，必要时采取相应护壁措施。c.基岩裂隙水基岩裂隙水主要赋存于基岩风化、节理裂隙内，其富水性极不均一，场地内基岩为白垩统朝川组含砾砂岩，层顶埋深约56.9～68.0m，泥质胶结，裂隙闭合性好，渗透性差。主要受侧向补给和上部承压水下渗补给，水量微弱，对工程影响不大。（2）渗透系数a.潜水含水层场地浅部粉土、粉砂层渗透系数的准确取值对基坑开挖、降水和围护影响较大。本次勘察取土样进行了室内渗透试验，其成果详见表2-3-2。表2-3-2土层渗透系数成果表层号土层名称渗透系数（cm/s）khkv1-1粘质粉土6.23E-055.9E-051-2砂质粉土8.1E-057.8E-051-3砂质粉土8.7E-058.2E-052-1砂质粉土9.4E-058.8E-052-2砂质粉土1.5E-041.1E-043-1粉砂夹粉土2.3E-041.7E-043-2砂质粉土7.05E-056.6E-053.3不良地质作用及不利于建设的地下埋藏物拟建场地早阶段为钱塘江河口冲海积形成的滩地，经后阶段人工围垦而成，地势较平坦、开阔，场地内及附近没有滑坡、崩塌、地面沉降、地面塌陷等不良地质作用。本场地分布大面积填土，局部分布有明（暗）塘（浜）、浅层沼气和饱和粉（砂）土液化，在原厂房和住宅区遗留有浅基础，无其它不利于建设的地下埋藏物。（1）大面积填土场地局部已经进行整平，与原始地形比较，场地大部分有新近回填土分布，厚一般0.5～2.5m左右，填土性质较松散，均匀性较差，对桩基施工会产生一定影响，如大面积沉降对桩的负摩阻力等。场地北面及东面防洪堤附近填土较厚，厚约4.0~12.0m，填土历时较长，性质尚可。综合考虑地下室开挖及桩基承台埋深等因素，一般填土均已挖除，填土引起桩负摩阻力的可能性小，局部填土厚度较大处，可对剩余填土进行换填或夯实处理，并尽量减小附加荷载的影响。andmasonryonthecorneroffice,inprinciple.Staggered,two-storeybrickverticalseamson25mm.Halfabrickusedseparately.(3)infrontofthewall,firstinstallcounting,countingpolesmarkthebrickthicknessofmortarjointthickness,doorandwindowelements,suchasdeepposition,countingpolesstandonthecorner.Statelevelwhencopyingflat,floorelevationsinleatherbardesignelevationposition.(4)whenbricksfirstalignment,masonrybricksaccordingtoguidelines.Apartfromhalfabrickwall,anddouble,tobettercontrolthewallflatness.(5)whenbuilt,the"31"masonrymethod,thatis,"anashshovel,brick,kneadandknead"methodofoperation.Verticalrollmethodisused.Verticalseamsofthemortarasfullaspossible,ventilationarenotallowed.Brickwallsofhorizontalmortarjointthicknessandverticalmortarjointwidthcontrolinthe8~12mmrange.Horizontalmortarjointmortarfullsizemustbegreaterthan80%.(6)fromcornerorpositioningatbegan,bothinsideandoutsidewallwhilemasonry,aspectwallstaggeredtakereceived;outsidewallcorneratisstrictlyprohibitedleftstraightrub,shouldbefromtwoaaspectswhilemasonry;wallbodytemporarycontinuousatshouldmasonryintoobliqueCha,obliqueChalengthnotshouldislessthanheightof2/3(Generalbyastepscaffoldingheightcontrol);asleftobliqueChahasdifficult,exceptwallcorneratandtheseismicfortificationarea,wallbodytemporarycontinuousatnotshouldleftstraightChaoutside,canfromwallsurfaceout200mmmasonryintoyinandYangCha,andalongwallhigheachthreeskinblock(600mm),Atiebarorsteelmesh.Chasiteshouldbedeferredtothejambs.(7)thebrickwallsandcolumnsper50cmsettingφ6thruwallshouldertiebar,halfbrickwallsmustbesetone,andatleastnotlessthan2,extendingintothebrickwallnotlessthan1M.(8)topsurfaceofcontactwiththeupperbeamoftheframefill,usingbrickskewtunneljam.(9)thewidthislessthan1Mwindowwall,usewholebricks.(10)reserveconstructionofholeinthewallwidthislessthan1M,andalongtheheightφ6@500allow2tiebar.8.6measures(1)strictlyaccordingtothenational,industry...Pressurepipeandthemetalstructureinstallation9.1mainengineering11 （2）明（暗）塘（浜）场地东面靠近主体育场二层平台自南向北分布有一小河（钻孔SZ185、SZ202、SZ203、SZ243、JZ262、SZ297、SZ322、SZ323所包含范围），河宽20m左右，已回填；北面有一东西向长条形暗塘（钻孔SZ46、SZ47、SZ64、SZ62、ZK7、SZ77、SZ93、SZ94所包含范围），长约145m，宽约5~25m；西面有一东西向长条形水塘（钻孔SZ141、SZ157、SZ170附近），水深约0.20~0.50m。河道、水塘底部有少量塘泥，对基坑工程有一定影响，施工时应进行排水、清淤，分层回填、压实处理。（3）浅层沼气根据区域资料，浅层沼气主要分布在淤泥质粘土层粉砂透镜体中，本次勘察过程中未发现，初勘时在静探孔JK5中发现，气量较小，施工结束1天后不再有气体冒出现象。（4）饱和粉（砂）土液化根据液化判别结果，在7度抗震设防烈度条件下，场地饱和粉土、粉砂会产生轻微液化~中等液化，主要液化土层为3-1粉砂夹粉土层，局部1-2、2-2砂质粉土个别点也会液化。本工程基础拟采用穿过液化土层的桩基方案，液化土层对工程影响较小。andmasonryonthecorneroffice,inprinciple.Staggered,two-storeybrickverticalseamson25mm.Halfabrickusedseparately.(3)infrontofthewall,firstinstallcounting,countingpolesmarkthebrickthicknessofmortarjointthickness,doorandwindowelements,suchasdeepposition,countingpolesstandonthecorner.Statelevelwhencopyingflat,floorelevationsinleatherbardesignelevationposition.(4)whenbricksfirstalignment,masonrybricksaccordingtoguidelines.Apartfromhalfabrickwall,anddouble,tobettercontrolthewallflatness.(5)whenbuilt,the"31"masonrymethod,thatis,"anashshovel,brick,kneadandknead"methodofoperation.Verticalrollmethodisused.Verticalseamsofthemortarasfullaspossible,ventilationarenotallowed.Brickwallsofhorizontalmortarjointthicknessandverticalmortarjointwidthcontrolinthe8~12mmrange.Horizontalmortarjointmortarfullsizemustbegreaterthan80%.(6)fromcornerorpositioningatbegan,bothinsideandoutsidewallwhilemasonry,aspectwallstaggeredtakereceived;outsidewallcorneratisstrictlyprohibitedleftstraightrub,shouldbefromtwoaaspectswhilemasonry;wallbodytemporarycontinuousatshouldmasonryintoobliqueCha,obliqueChalengthnotshouldislessthanheightof2/3(Generalbyastepscaffoldingheightcontrol);asleftobliqueChahasdifficult,exceptwallcorneratandtheseismicfortificationarea,wallbodytemporarycontinuousatnotshouldleftstraightChaoutside,canfromwallsurfaceout200mmmasonryintoyinandYangCha,andalongwallhigheachthreeskinblock(600mm),Atiebarorsteelmesh.Chasiteshouldbedeferredtothejambs.(7)thebrickwallsandcolumnsper50cmsettingφ6thruwallshouldertiebar,halfbrickwallsmustbesetone,andatleastnotlessthan2,extendingintothebrickwallnotlessthan1M.(8)topsurfaceofcontactwiththeupperbeamoftheframefill,usingbrickskewtunneljam.(9)thewidthislessthan1Mwindowwall,usewholebricks.(10)reserveconstructionofholeinthewallwidthislessthan1M,andalongtheheightφ6@500allow2tiebar.8.6measures(1)strictlyaccordingtothenational,industry...Pressurepipeandthemetalstructureinstallation9.1mainengineering11

第三章总体施工顺序与空间组织针对本工程体量大、分阶段施工、主体育场工作面能同时提交的特点，在平面上我们以体育场按后浇带划分为A、B、C、D四个区域（见附图6），组织平行施工，考虑施工方便，第一检录处及能源中心与A区1-H～1-M处同步施工。正负零以下结构具体的施工步骤如下：（1）基坑工程施工阶段本基坑工程土方开挖分层分段进行，按“先撑后挖，先换撑后拆撑”和“大基坑小开挖”的原则进行。土方开挖分两期施工，以1-H轴~1-J轴之间的后浇带为界。分界线之内为第一期，分界线之外为第二期。共配备8台PC200挖掘机，局部坑中坑以及北侧水平支撑处，配备8台小挖机配合施工。待第一期上部主体结构及钢结构安装完成后，进行第二期深基坑施工。施工段具体划分如下：土方工程开挖总量约60万m3，第一阶段开挖面积约为50000m2，开挖土方量约为23万m3；第二阶段开挖面积（包括第一检录处及能源中心）约为50000m2，开挖土方量约为37万m3。基坑土方开挖分成两期进行施工，第一期土方开挖在钻孔灌注桩第一阶段ZA1区施工完成后插入；第二期土方开挖在钢罩棚吊装基本完成时插入施工。第一、二期挖土顺序见图4-1-1-2～3，第一期基坑工程施工顺序见图4-1-1-4。第一步第二步第三步第四步andmasonryonthecorneroffice,inprinciple.Staggered,two-storeybrickverticalseamson25mm.Halfabrickusedseparately.(3)infrontofthewall,firstinstallcounting,countingpolesmarkthebrickthicknessofmortarjointthickness,doorandwindowelements,suchasdeepposition,countingpolesstandonthecorner.Statelevelwhencopyingflat,floorelevationsinleatherbardesignelevationposition.(4)whenbricksfirstalignment,masonrybricksaccordingtoguidelines.Apartfromhalfabrickwall,anddouble,tobettercontrolthewallflatness.(5)whenbuilt,the"31"masonrymethod,thatis,"anashshovel,brick,kneadandknead"methodofoperation.Verticalrollmethodisused.Verticalseamsofthemortarasfullaspossible,ventilationarenotallowed.Brickwallsofhorizontalmortarjointthicknessandverticalmortarjointwidthcontrolinthe8~12mmrange.Horizontalmortarjointmortarfullsizemustbegreaterthan80%.(6)fromcornerorpositioningatbegan,bothinsideandoutsidewallwhilemasonry,aspectwallstaggeredtakereceived;outsidewallcorneratisstrictlyprohibitedleftstraightrub,shouldbefromtwoaaspectswhilemasonry;wallbodytemporarycontinuousatshouldmasonryintoobliqueCha,obliqueChalengthnotshouldislessthanheightof2/3(Generalbyastepscaffoldingheightcontrol);asleftobliqueChahasdifficult,exceptwallcorneratandtheseismicfortificationarea,wallbodytemporarycontinuousatnotshouldleftstraightChaoutside,canfromwallsurfaceout200mmmasonryintoyinandYangCha,andalongwallhigheachthreeskinblock(600mm),Atiebarorsteelmesh.Chasiteshouldbedeferredtothejambs.(7)thebrickwallsandcolumnsper50cmsettingφ6thruwallshouldertiebar,halfbrickwallsmustbesetone,andatleastnotlessthan2,extendingintothebrickwallnotlessthan1M.(8)topsurfaceofcontactwiththeupperbeamoftheframefill,usingbrickskewtunneljam.(9)thewidthislessthan1Mwindowwall,usewholebricks.(10)reserveconstructionofholeinthewallwidthislessthan1M,andalongtheheightφ6@500allow2tiebar.8.6measures(1)strictlyaccordingtothenational,industry...Pressurepipeandthemetalstructureinstallation9.1mainengineering11
