摘    要:采用实验、0实测及数值模拟方法,研究了关键层对覆岩及地表移动的控制作用和关键层破断块度对其位移曲线形态的影响,提出了“砌体梁”结构位移曲线的拟合方程;对关键层与表土层间耦合关系进行了研究,提示了关键层与表土层间合关系的一些基本规律,对改进地表下沉预计方法具有指导意义。

关 键 词:关键层  地表移动  耦合关系  覆岩  岩层移动  岩层

Abstract:Based on subsidence surveying,physical and numerical simulation,it has been tested that the strata movement and surface subsidence were controlled by the key strata;the influence of key strata broken length on the subsidence curve of the voussoir beam was studied,and the formula for the subsidence curve of the voussoir beam has been put forward;the coupling relation between the soil and the key strata has been studied, some suggestions to revise the surface subsidence prediction method have been put forward.
Keywords:key stratum  strata movement and subsidence  coupling relation between soil and key stratum
