摘要

在地铁隧道—地裂缝动力相互作用模型试验中

拟采用点荷载的加载方式。为了合理制定模型试验加载方案

建立了点荷载和移动荷载2种加载方式下

与地裂缝正交的马蹄形隧道—地裂缝—地层动力相互作用的数值模型。通过对2种加载方式下的拱底土层竖向最大位移、土层最大加速度分布、土层加速度时程以及衬砌加速度时程进行对比分析

可以得出在2种加载方式下

拱底竖向最大位移、土层加速度分布、土层加速度时程以及衬砌加速度时程在分布上有相近的规律

从而说明了在模型试验中

可以用点荷载加载方式来代替移动荷载

为模型试验提供了依据。

Abstract

In the subway tunnel-ground fissures dynamic interaction model test

point load loading way is proposed.In order to determine the loading plan of the model test

the point loads and moving loads

the two kinds of loads are used in the ground fissures-orthogonal U-shaped tunnel dynamic interaction numerical model.Through the two loading modes

the maximal vertical displacement of the arch bottom soil

soil maximum acceleration distribution

soil acceleration time history and acceleration time history of the lining are analyzed and compared.It is concluded that

under the two loading modes

the maximal vertical displacement at the bottom of the arch

the soil acceleration distribution

soil acceleration time history and the acceleration time history of the lining have similar distribution regularity.Thus it is illustrated that in the model test the point load loading method can be used in place of the moving load.It provides the basis for the model test.
