| 摘 要： | 对采空区地表沉降量进行预测分析并提出了高压旋喷桩的加固方案及加固设计计算。工程实例表明,高压旋喷桩对地表沉陷引起的地基承载能力下降及不均匀沉陷有很好的控制作用,其加固方案可为同类工程参考。

| Abstract: | This paper predicts and analyzes the settlement of earth surface in mined-out area and puts forward the reinforcement program and design calculation for high pressure jet grouting pile.Engineering examples indicate that high pressure jet grouting pile has good control effect on reduction of foundation bearing capacity and uneven settlement caused by earth surface settlement.This reinforcement program can provide reference for the similar engineering. |
