交通枢纽基坑群“坑中坑效应”机理分析与影响计算

摘要

The paper described the"pit-pit effect"of a large transportation hub project, and by example, took the numerical simulation calculation of the coupling and overlay effect; at last, we concluded the regularity of deformation of retaining structure in and around the surface under"pit-pit effect".%　　本文介绍大型交通枢纽工程中“坑中坑效应”，并通过实例对其耦合叠加作用进行了数值模拟计算，得出了“坑中坑效应”下，围护结构及周边地表发生变形的规律。
