边坡土钉墙支护设计的理论及其应用

Theories and Application of the Slope Soil Nail Wall Support Design

通过对工程存在边坡各项参数的分析,在土体内设置一定长度和密度的土钉,使土钉与土共同作用,这样不仅有效提高了土体的整体刚度,又弥补了土体抗剪、抗拉强度低的弱点,形成一种主动制约机制的支护结构,显著地提高了整体稳定性,改善了土体的塑性变形和破坏性状。

By the analysis of various parameters of slope,enough length and density soil nails are set to make the soil nail and soil working together.This can effectively improve the integrate rigidity of soil,increase shear strength and tensile strength of soil to form a kind of active restrict support structure.This method evidently improves integrity stability,changes plastic deformation and destructiveness form.
