地表沉陷
The development of the rheological theory and computer technology provide a sound base to understand the movement law for mining overburden strata and surface subsidence.
流变力学理论和计算机技术的发展，为从理论方面了解覆岩移动的和地表沉陷的动态变化规律提供了前提。
地表塌陷
The failure of thick sandy soil layer spreads to the ground surface in shallow seam mining, which will cause heavy disasters, such as dynamic ground pressure in coal faces and ground surface subsidence.

地表下沉

地表沉降
We begin this paper with introduction of the actuality of forecast of the surface subsidence, followed by discussion of the techniques of both grouting and monitoring. Some monitoring methods of surface subsidence will be investigated in details afterward.
本文首先介绍了目前国内外沉降预测的研究现状,研究了与工程相关的注浆技术和监测技术,收集了上海地铁某隧道壁后注浆施工资料,整理了地表沉降的监测数据。
回落
There are many methods to study the surface subsidence. We choose the monitoring data method to evaluate the grouting effects because the purpose of this paper is how to get the useful information from these monitoring data.
本文结合注浆及监测资料,从统计学的角度深入分析了地表顶升回落规律,评价了注浆效果。
