摘要

讨论了不同岩层组合条件下离层带注浆充填时地表下沉的预计问题 ,分别考虑了 :( 1)岩层水平成层和倾斜成层 ;( 2 )注浆密实和部分未注浆 ;( 3)顶部岩层坚硬 ,在各方向上压缩相同和顶部岩层软弱 ,浆液向后充填和上山方向挤出 ,各方向上压实不等的各种情况 .简要介绍了采用地震波场对离层带浆液充填情况的探测原理 ,并据此进行地表沉陷的预计工作
An estimation formula for surface subsidence under the condition of bed separation gaps filled by grouting and different strata combinations is presented. The following factors have been considered:(1) horizontal and inclined strata;(2) tightness of grouting and partial absence of grouting;(3) stiffness and weakness of top strata (the former refers to the identity of compression in all directions, the latter indicated that grouting liquid is filled in the rear packing area and squeezed towards the rise), and various other conditions such as unequal pack tightness of filling material in all directions. The laws of the inspection of grouting effect are indroduced. Practice has proved the reliability of calculation.
