摘要
根据深圳地铁一期工程中国贸—老街区间的地质资料及设计文件 ,针对单洞双层隧道施工开挖及其对基础托换桩的影响 ,利用有限元法对施工期的地表沉降及托换桩水平位移等力学行为进行了模拟和分析 。
According to the geological data and design documents of Guomao\|Laojie section first stage subway in Shenzhen, simulation and analysis were performed on such mechanical behaviors as earth surface settlement and horizontal displacement of underpinning pile by three\|dimension nonlinear finite element method, which may provide instructions for design and construction.
