基　　金：安徽省自然科学重点项目“复杂环境下深基坑开挖过程中基坑位移变形和基坑支护优化方案的研究”(项目编号:2023AH051159);淮南联合大学校级科研项目基于Midas深基坑开挖的模拟分析(项目编号:LQN2003)。

摘　　要：随着地下建筑的开发,深基坑工程也日益增多,而单排桩加内支撑是深基坑工程中常见的支护形式,具有较强的现实研究意义。以深基坑开挖项目为例,通过Midas Gen模拟深基坑整个开挖过程及现场测量的方法,得出地表沉降、基坑坑底竖向位移、围护墙体水平位移及支护桩体弯矩的变化规律,同时进一步证实了Midas模拟的有效性。With the development of underground buildings,there are more and more deep excavation projects,and single row piles with internal support is a common form of support in deep excavation projects,which has strong practical research significance.Taking the deep foundation pit excavation project as an example,Midas Gen was used to simulate the entire excavation process of the deep foundation pit,and the simulated values were compared and analyzed with on-site monitoring values.The changes in surface settlement,vertical displacement of the foundation pit bottom,horizontal displacement of the retaining wall,and bending moment of the support pile were obtained,providing a theoretical basis for deep foundation pit excavation support and further confirming the effectiveness of Midas simulation.
