The measurement results show that there is really a distortional boundary layer displacement surface on the ground board, and it fully differs from natural growing boundary layer on the ground board.
测量结果表明：在地板上确实存在一个畸变的附面层位移面，它与自然增长的地板附面层截然不同。
However, the displacement and deformation of surface ground by underground mining have destroyed initial equilibrium between the building and the ground.
但是由于地下开采引起地表产生的移动和变形，破坏了建筑物与地基之间的初始平衡状态。
For the safety and normal usage of the city ground building, therefore it is extremely important to estimate the earth surface movement and displacement caused by tunnel construction.
为确保城市地面建筑的安全和正常使用，因此对隧道施工所产生的地表位移的预测极为重要。
