摘　　要：运用FLAC3D对受百善矿6123首采工作面开采影响而引起的南沱河河堤(以北堤为例)的垂直位移进行数值模拟,得出河堤断面上各监测点的最终下沉量,为河堤的加固和设计加高培厚的断面提供科学依据。This paper mainly uses FLAC3D to simulate the Z displacement of the Nantuo riverbank because of 6123 which the first workfaee mining subsidence in Baishan mine, then we can get the finally subsidence data of each point on the riverbank, and this will provide scientific gist for reinforcing the bank.
