高层建筑基坑支护结构破坏原因主要有 :支护结构整体失稳、基坑土体隆起、管涌及流沙的出现、支撑强度不足或压屈、墙体破坏、支护结构平面变形超过限度。某大厦施工中由于桩身强度不足、桩尖达到的深度不够及桩间距过大等原因 ,致使管涌发生 ,造成塌方。通过对事故针对性的处理 。
This areicle has studied the causes of the backing structure of the measures base holes through examples,meanwhile it also introduces the measures that we should take to deal with the failure of the backing structure of building that we shoule take to deal with the failure of the backing structure of building base holes.
