| 摘 要： | 软土基坑工程的"时空效应"是近年来基坑工程研究和实践的重大创新成果,而"空间效应"则是"时空效应"的重要组成部分。随着开挖深度和面积的急剧增大,软土深基坑工程的"空间效应"愈加显著,基坑变形控制和周边环境保护愈加困难。通过紧邻地铁超深基坑工程施工的实例分析,论述了"空间效应"原理在软土深基坑工程中的应用,取得了很好的变形控制效果,保证了临近运营地铁的安全,对类似软土深基坑工程具有一定的指导意义。

| Abstract: | Time and space effect of deep foundation pits in soft soil areas is one of the great study and practical achievements.It includes Time effect and Space effect.With the rapid increase of excavation depth and area,the Space effect has become more and more obvious,and the deformation control and environment protection have become more and more difficult.A construction case of deep foundation pit close to running subway tunnels was demonstrated according to the Space effect theory.The deformation of retaining s... |
