| 摘 要： | 煤矿输煤暗道基坑开挖时造成临近主井驱动机房倾斜和基坑边坡垮塌。采用钢筋混凝土预压托换桩对原主井驱动机房基础加固,通过托换桩将机房荷载传递到承载力较好的持力层,既保证了既有建筑物的安全,又保证了边坡的稳定,加固效果可靠,取得了良好的经济与社会效益,为既有建筑近旁开挖深基坑的边坡支护方法的研究与工程应用方面取得了成功的尝试。

| Abstract: | When a coal mine dug foundation pit for blind pass of coal transportation,the nearby main machine room inclined and the side slope of foundation may collapse as a result of digging.In this paper way was figured out to solve this problem.Steel concrete pretest pile was applied to reinforce the primary main machine room,then the load was transmitted to bearing layer which had a better carrying capacity.As a result,the safety of buildings and stability of side slop were ensured;what's more,the achievement of r... |
