运用三维快速拉格朗日差分软件FLAC3D研究了当弹性半空间体内存在隧道时，布辛奈斯克解的适用性，通过布辛奈斯克公式计算得到了弹性半空间表面在均布矩形荷载作用下的地表沉降，与FLAC3D计算得到的结果进行对比，验证了运用FLAC3D对该问题进行研究的可行性，并指出在运用布辛奈斯克公式计算含有隧道的土体地表沉降时，应充分考虑隧道埋深及其支护刚度的影响。

The applicability of the Bubuxinneske solution in the case of the existence of tunnel in the elastic half space has been researched by using three-dimensional fast Lagrangian finite difference software FLAC3D . First by Boussinesq’s formula to calculate the surface subsidence un-der uniform rectangular load in the elastic half space,and then compared with the results calculated by FLAC3D ,verify the feasibility of using-FLAC3D to study the problem. Pointed out that the influence of buried depth and support stiffness should be fully considered when it calculated the buried depth of the soil containing tunnels using Boussinesq’s formula.
