摘要
随着城市地铁交通的发展,下穿浅埋地铁隧道的基坑工程时有发生。以实际工程为例,对基坑支护结构形式的比选、理论设计以及基坑的有限元数值模拟进行详细阐述。通过数值模拟结果与现场监测数据,可知本案例的支护方案是成功的,在满足安全的前提下,极大缩小了工期,取得了预期的经济效益。
With the development of urban subway traffic,foundation pit engineering under shallow metro tunnel often occurs.Taking the engineering project as an example,this paper elaborates on the comparison and selection of the supporting structure of the foundation pit and the theoretical design,the finite element simulation of the foundation pit.The results of numerical simulation and field monitoring data show that the supporting scheme is successful.Under the premise of safety,the construction period is greatly reduced and the expected economic benefits are obtained.
