基于关键层理论的沉陷变形起动距的确定

Determination on starting distance of subsidence deformation base on key strata theory

根据关键层理论判定关键层及其破断规律,研究地表下沉起动距与关键层初次破断距之间的关系。比较实测起动距与主关键层初次破断距计算值之间在时间和大小上的差异,分析造成这种差异的原因,确定理论计算沉陷变形起动距的科学方法。

According to the key strata theory to judge the key strata and the failure and broken law, the paper studied the relationship between the starting distance of the surface subsidence and the initial broken distance of the key strata. The paper has a comparison on the timing and difference between the actual measured starting distance and the primary broken distance calculated value of the key strata. The paper analyzed the difference causes and determined the scientific method for the theoretical calculation of the starting distance of the subsidence deformation.
