摘要
土钉支护软土边坡(壁)具有良好的经济效果,但在松散的砂土、淤泥质类软弱土及高地下水位的地层中使用时,土钉常常不能有效地发挥其支撑能力,引起严重的施工问题。为保证基坑施工的安全、快速,通常采用复合土钉墙等施工技术,即土钉与其它支护结构共同作用即复合土钉墙以提高基坑边坡的稳定性,文中详细介绍了复合土钉墙的工程应用。
Though soil-nailing has a good economical effect in protecting soft soil slope or wall,its supporting capacity can not be effectively utilized when applied to loose or muddy soft soil as well as to the stratum with high un- derground water level and would bring about serious problems to construction.In order to guarantee the construction of foundation pit safely and quickly,the technique of composite soil-nailing wall is usually used.that is,the soil- nailing and other supporting member's structure are used together to enhance the stability of foundation pit slope.The apphation of composite soil-nailing wall is introduced in details in this paper.
