| 摘 要： | 水泥土复合式支挡结构是一种在水泥土搅拌桩墙体中插入钻孔灌注桩并架设内支撑的新型支挡形式.本文在分析其支挡特点及有限元程序设计的基础上,通过方案设计与其它支挡形式进行了比较,并将之应用到了实际工程中去;理论和实践证明,水泥土复合式支挡结构在控制墙体位移、坑底隆起、周围地面沉降及内支撑拆除后这些指标的变化等方面有其明显的优越性,其造价适中,建议在软土地区基坑工程中进一步推广.

| Abstract: | In this paper, a kind of composite braced retaining structure system ( CERSS ) is introduced, which is composed of struts and cement-agigating-pile retaining wall inserted by cast-in-place piles. Based on the peculiarities of this system, its FEM programing design and project design, it is compared with other retaining structures. It is proved by theory and practice that this kind of CERSS 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, so that it can be further put into use in excavation engineering in the soft soil area. |
