摘　　要：大型基坑土方开挖难度较大,主要体现在工程量大、场地环境差、流沙、流土可能性高等方面。本文以武汉某一工程实例为参照,尝试通过分区开挖、调整开挖顺序、分阶段开挖等多种方式优化土方开挖流程。从工程结果表现上,该操作已达到预期效果,希望相关施工经验能够对同类型作业有一定的参考作用。It is difficult to excavate large foundation pit earthwork,which is mainly reflected in the large amount of engineering,poor site environment,and high possibility of quicksand and flowing soil.Taking an example of a project in Wuhan as a reference,this paper tries to optimize the earthwork excavation process by zoning the excavation,adjusting the excavation sequence and excavation by stages.From the performance of the engineering results,the operation has achieved the expected effect,I hope that the relevant construction experience can have a certain reference role for the same type of operation.
