太原市基坑工程常见问题与处理实践

Common problems and treatment practice of excavation engineering in Taiyuan City

为确保基坑工程这一危险性较大的分部分项工程的作业安全,以山西省太原市典型基坑工程案例为研究对象,积极探究区域岩土特性条件下基坑工程设计、施工、监测等方面的相关问题与解决办法。提出了基坑工程应注重基坑侧壁水土条件、周边环境影响、基坑施工工序及周边作业条件等因素,结合岩土计算及既有工程类比完成基坑支护选型及现场作业,同时应尽可能利用现有信息化手段对基坑工程进行动态监控并反馈施工,从而确保基坑工程在达到经济与安全相协调的同时,能够顺利推进完成。

In order to ensure the safety of excavation engineering which is a dangerous sub-project,the typical case of excavation engineering in Taiyuan is taken as the research object and the relevant problems and solutions of excavation engineering design,construction and monitoring under the conditions of regional geotechnical characteristics are actively explored.It is proposed that foundation pit engineering should pay attention to the factors such as soil and water conditions on the side wall of foundation pit,the influence of surrounding environment,the construction process of foundation pit and surrounding operation conditions,and complete the selection of foundation pit support and site operation in combination with geotechnical calculation and existing engineering analogy.At the same time,the existing information means should be used as much as possible to dynamically monitor and feedback the construction of foundation pit engineering.So as to ensure that the foundation pit engineering can be successfully completed while achieving the coordination of economy and safety.
