摘要
以兰州地铁1号线试验段世纪大道站深基坑为依托,针对兰州特有的深厚砂卵石地层地下水处理方案、围护桩成孔工艺和围护结构设计方案进行基坑施工过程数值模拟及现场监测数据对比分析。通过对关键技术进行系统研究,提出设计和施工的优化方案,丰富现场信息化施工的相关资料,为相似地层的车站基坑设计与施工提供借鉴和参考。
Base on the deep foundation pit of the test section Century Avenue station in Lanzhou metro line 1aiming at Lanzhou peculiar deep sandy gravel stratum,the key technologies such as the groundwater treatment scheme,the hole-making technology of retaining pile,the design scheme of enclosure structure were studied to simulate the foundation pit construction process,compare and analyze the field monitoring data.Through the systematic researched on the key technologies,the optimization schemes of design and construction were put forward,meanwhile,the related data of field information construction were enriched.The reference for design and construction of the foundation pit under the similar stratum condition were provided in this paper.
