为避免应用常规管井井点进行筏板基础降水时,因管井井点的存在,而对筏板基础局部区域的混凝土连续性和整体性的施工造成影响,和在该处容易产生混凝土质量和防水质量缺陷的问题,结合工程实例,提出筏板基础管井井点降水套筒施工技术.此工艺简单易操作,集降水与封井于一体,保证了降水井点处筏板混凝土施工的连续性和整体性,提高了施工效率和施工质量.

平潭高铁中心站综合交通枢纽及高铁中心站站前城市综合体项目,基坑面积大,开挖深度深,地质条件差,周边环境复杂,给基坑方案选型和土方开挖带来一系列技术难题.通过采用分区分级支护技术,根据不同区域施工条件,分2级卸荷土方,分级支护,并采用盆式土方开挖方法,成功解决了相关难题.施工结果表明,分级支护结合盆式开挖可以避免设置大面积水平支撑,有效地缩短了基坑及地下空间结构的施工工期,减少了工程造价,总结的经验可为软土地区超大深基坑设计和施工提供参考.
为解决某些特殊工况下,现场条件导致围护体系无法彻底隔断承压水层,基坑开挖又要求必须进行降水作业,导致基坑安全要求同周边环境保护要求之间的矛盾,介绍了一种运用超高压喷射搅拌成桩工法水平隔断承压水的施工技术.该技术运用于上海市某地铁车站工程中,成功隔断了不同层承压水之间的联系,确保了基坑安全,总结的经验可供类似工程参考.
结合武汉智能网联汽车测试场项目,以理论分析和数值计算为手段,比较分析了有桩帽的CFG桩与无桩帽的CFG桩复合地基的变形及受力的差异,进而分析了桩帽的尺寸及强度对复合地基以及桩间土的影响.研究结果表明:桩帽改变了复合地基桩及桩间土的受力和变形;桩帽的尺寸越大,桩顶的位移越大,桩间土的位移越小;桩帽的强度越大,桩顶位移及桩间土的位移越小,当桩帽强度等级大于C30时,桩帽强度的影响力变小.
