Subway station deep foundation pit construction method under water-rich geological condition
The invention relates to the technical field of subway construction, in particular to a subway station deep foundation pit construction method under the water-rich geological condition. The construction method comprises the following steps that S1, a construction site is planned and arranged; S2, pipeline cutting and changing are carried out; S3, underground diaphragm wall construction is carried out; S4, foundation pit excavation numerical simulation is carried out; S5, a foundation pit is excavated, wherein S51, the foundation pit is dewatered; and S52, earth excavation is conducted. According to the construction method, influence analysis and scientific simulation analysis of complex geological conditions on the subway station are carried out, such that risks possibly encountered in the construction process can be avoided, the construction safety is improved, the construction quality and the construction process safety are guaranteed, construction accidents are avoided to the maximum extent, and the construction efficiency is remarkably improved. The method is mainly applied to subway station deep foundation pit construction under the water-rich geological condition.
本发明涉及地铁施工技术领域，更具体而言，涉及富水地质条件下地铁车站深基坑施工工法。包括以下步骤：S1、施工场地规划及布置；S2、管线切改；S3、地下连续墙施工；S4、基坑开挖数值模拟；S5、基坑开挖：S51、基坑降水；S52、土方开挖。本施工工法进行复杂地质条件对地铁车站的影响分析，科学的模拟分析，能够规避施工过程中可能遇到的风险，提高了施工安全性，保证了施工质量，施工过程安全，最大程度的避免了施工事故的发生，显著提高了施工效率。本发明主要应用于富水地质条件下地铁车站深基坑施工方面。
