摘要
本文以福州市某下穿地下通道工程为背景,结合相似工程的设计资料与地勘报告,通过计算机数值模拟,分析了预应力管桩和水泥搅拌桩两种软基处理方式,在不同软土地区、不同阶段(施工和运营)地下通道的沉降规律和特性,归纳出三个变量对沉降的影响,并提出设计应注意的事项和要点,可为软土地基上建设类似工程设计提供参考。
Based on the project of Linpu Rd underground expressway in Fuzhou area and the survey & design documents from other similar projects, some nu- merical simulations that differ from ground condition and operation condition are carried out. The mechanical responses of subgrade/pile and the uneven settle- ments between segments are well studied, which can provide some optimal designs for other similar projects.
