基坑开挖及降水引起周围建筑物不均匀沉降的实例
基坑开挖及降水引起周围建筑物不均匀沉降的实例
摘要:在建筑物较近处，放坡开挖8．0m的基坑，由于降水、开挖及雨后土体强度的降低，引起建筑物不均匀沉降，通过实测发现，降水引起的地面沉降影响范围约为井深的1．5倍；放坡开挖引起的地面沉降影响范围约为坑深的3－4倍，以及雨后土体强度降低会进一步加强土体变形等结论。
Abstract:A 8. 0(m) deep excavation is constructed without any protection immediately adjacent to the building. Because of precipitation the nonuniform settlement for the existing building is brought about when the strength of soil body reduces after the excavation and rain. According to the actual observation, the affected area for ground settlement arisen form precipitation is about 1. 5 times of well depth, the affected area arisen form no-protecting excavation is 3~4 times of pit-depth, and the deformation of soil mass further increases with the reduction of its strength after rain.
