河北工业大学教学主楼基坑支护结构分析

Analysis of the Braced Retaining Structure in Main Teaching-build of Hebei University of Technology

在对水泥土搅拌桩支挡结构,混凝土悬臂桩支挡结构,水泥土复合支挡结构这3种设计方案的特点进行比较分析的基础上,通过有限元程序的理论计算和现场监测的结果,证明了在软土地区的浅基坑开挖中,水泥土搅拌桩支挡结构在控制墙体位移、坑底隆起、周围地面沉降等方面有其明显的优越性.并且造价适中,保证施工工期.

It is compared with the peculiarities of the cement-agitating-pile retaining structure, concrete-can-tilever-pile retaining structure and cement-soil composite brace retaining structure. Based on the FEM theory calculation and sport measure, this kind of cement-agitating-pile retaining structure has an obvious advantage in controlling the displacement of retaining wall, heave of excavation base and settlement of surrounding ground surface, as well as their changes after the struts have been removed. The cost of the retaining structure is proper in excavation engineering of the soft soil area.
