几个工程实例表明，在基坑中设置横墙可以有效地减少墙体的挠度和地面沉降。然而，由于横墙的安装，地下连续墙的行为仍然不清楚。本文对带横连墙的深基坑开挖进行了三维数值模拟，研究了横连墙数量、横连墙间距、横连墙高度、横连墙埋深等参数对基坑开挖变形的影响。本研究的结果可作为横墙设计以减少深开挖引起的墙体变形的第一近似值。
Several case studies have revealed that the installation of cross walls in excavations can effectively reduce the amount of wall deflection and ground settlement. However, the behaviour of the diaphragm wall due to the installation of the cross walls is still unclear. This study performed a series of 3D numerical studies of wall deflections for deep excavations with cross walls and studied the effects on the wall deflection of several parameters, including the number of cross walls, the distance to the cross wall, the cross wall interval, the cross wall height and the cross wall embedment. The results presented in this study can be used as a first approximation for cases in which cross walls are designed to reduce the wall deflection induced by deep excavation.
