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。

We calculated the surface subsidence, horizontal displacement, incline, and current curvature using the groundwater drawdown, conical depression influence radius of water cone and ground property.

根据地下水降深、降落漏斗影响半径、岩土工程地质性质，计算降水引发的地表沉降值、水平移动、倾斜、曲率现状值。
