摘要
为研究搅拌桩对复合土钉墙整体稳定系数的影响,采用以普通土钉墙整体稳定验算方法为基础并考虑搅拌桩抗剪作用的复合土钉墙整体稳定性验算公式,对分布在深圳和广州等地的14个复合土钉墙工程进行了计算,得到了3类整体稳定系数与搅拌桩长度之间的曲线规律。分析结果表明:搅拌桩对复合土钉墙整体稳定系数的提高作用明显,建议按照提高比例不大于30%进行工程验算。
Abstract： In order to study the soil nailing wall, based on the influence of mixing piles on base checking method of base stabilit stability coefficient of composite y coefficient of the common soil nailing wall, the checking formula of the composite soil nailing wall was added with the consideration of the shear capacity of mix piles. The calculation was conducted about the 14 projects mainly located in Shenzhen, Guangzhou and other areas. Three types of curve laws between the base stability coefficients of composite soil nailing walls and the length of mix piles were obtained. The analysis results show that it is obvious for the base stability coefficient increment of composite soil nailing walls, and it is suggested that the increment percent should not be more than 30G for mix piles in practice.
