摘要: 某市政工程地处长江一级阶地地貌单元,分布着深厚的软弱土层。该工程既有地基处理也有基坑支护。〖JP2〗如果地基处理和基坑支护单独进行设计,则工期长、造价高。而采用格构式水泥搅拌桩进行地基处理兼做基坑被动区加固设计,在技术、经济和工期上均具有很大优势。实践证明该设计达到了预期功能及目的,可供类似工程借鉴。

Abstract: The subsurface condition of a municipal engineering project consists of thick soft cohesive soil of the first terrace of Yangtze River. Both the deep excavation and the soil improvements are required for the project. A high construction cost and extended construction period were expected if the soil improvement and the deep excavation supporting system were designed and constructed separately. Using the grid formed soilcement mixing columns as the soil improvement and the strengthening of the passive zone of the excavation supporting zone has the advantages in both cost and the construction schedule.
