摘要
针对滨江富水地区水利工程的顶管及配套基坑施工过程,建立对既有下穿盾构影响的仿真受力模型,模拟顶进过程及基坑分步降水等重要施工参数,研究顶管周围环境的变化规律.分析显示:数值模拟的定性分析对水利工程的施工方案提供了指导意见,将滨江地区水利工程施工引起的影响控制在了合理的安全性要求范围.
Abstract
Aiming at the construction process of pipe jacking and supporting foundation pit of the water conservancy project in the water-rich area of the river,a simulation stress model for the influence of the existing underpass shield was established,and important construction parameters such as the jacking process and the step-by-step precipitation of the foundation pit were simulated.The change law of the surrounding environment of the pipe jacking.The analysis shows that the qualitative analysis of the numerical simulation provides guidance for the construction plan of the water conservancy project,and controls the impact caused by the construction of the water conservancy project in the Binjiang area within a reasonable range of safety requirements.
