摘 要: 结合某桥闸重建工程实例,分析了基坑开挖施工过程中和回填土没有完成之前基坑周边发生沉降的机理及引起沉降的原因,针对施工沉降进行观测并提出了控制沉降的相应措施,以使沉降量控制在一定范围内。 Integrating with a bridge-brake reconstruction practice, it analyzes the settlement mechanism around foundation pit and settlement causes in the process of excavation and before filling the foundation pit. It carries out an observation in light of construction settlement, and proposes corresponding measures, so as to control the sum of settlement within a certain range.
