三、地质情况Geologicalconditions
(1)地基土的构成与特征
根据勘探孔野外编录资料及静力触探曲线,结合土工试验成果,按岩土单元层成因时代、埋藏条件、岩性特征及物理力学性质的差异等、将勘探深度及浅土体划分为8个岩土土体单元层和分属不同单元层的亚层。
自上而下分别为:
1层素填土,
2浜填土,
1层粘土,

(2)地下水、地表水
嘉兴地区历年最高水位为2.80m
场地浅部土层中的地下水属于潜水类型,浅部粘性土层富水性差,其水位动态变化主要受控于大气降水和地面蒸发,地下水位明年变化幅度在1m左右。
勘察期间,实测孔内的地下水初见水位埋深在1.8m~2.7m之间,相应标高为-0.25~0.65m。
静止水位埋深在0.25~1.3m之间,相应标高为1.18m~2.2m。

第三章开挖前准备工作
Thethirdchapterpreparationworkbeforeexcavation
一、现场施工条件constructionconditionsofSite
本项目位于浙江嘉兴经济技术开发区马家浜路以西,320国道绿化带以南,圣堂路以北地块。
场地平整已基本完成。
现场出入口位于工地南圣堂路、东北角马家浜路两出入口。
地内自然地坪标高均在2.9m之间。
根据工程特点及现场实际情况,土方开挖采用场内短驳方式。

四、做好基坑表面硬化及排水措施Dotheexcavationsurfacehardeninganddrainagemeasures
根据地勘报告及场地实际情况,地表土以黄粘土为主并且含水量较大,故采取基坑表面硬化(6m宽施工道路)方便出土及合理的排水措施。
出土口硬化地坪做法为:
素土夯实铺60厚建筑砼碎块平整夯实。
排水措施:
基坑坑底四周边挖边由人工开挖300宽明沟,并在基坑四周每隔30m设500*500mm的集水坑,m9网。

五、技术措施technologymeasures
认真学习±0.000m以下结构图纸、工程地质勘察报告,知晓场地内土质、水文情况,核对基坑内各部位的开挖深度,与土方开挖单位共同编制土方开挖专项施工方案。
会同甲方、设计、监测、监理各单位对各种可能发生的情况进行预估和对策分析,制定详细可行的施工应急措施和方案。

第四章土方开挖施工工艺
Theforthchapterexcavationprocess
一、开挖方式选择choosethemethodofexcavation
根据本工程的特点及土质地况,采用机械场内短驳方式。
Accordingtotheengineeringcharacteristicsandsoilcondition,wewillchoosemachinecarrysoilandstackitonsite
采用机械和人工相结合进行并采用端头挖土法:
挖土机从基坑(槽)或管沟的端头以倒退行驶的方法进行开挖。
自卸汽车配置在挖土机的边侧装运土,自卸汽车停在机旁装土内短驳。
机械挖土预留20cm~30cm厚土,由人工紧跟其后进行修挖至设计垫层底标高。
土方挖出后,短驳堆放至2#生产厂房东北测、西北侧两旁。
