摘要
介绍了在强风化泥岩、角砾岩滑坡中锚索的二次高压劈裂注浆工艺,从宏观和微观角度分析其全面提高土体的C,ψ值、剪切滑动面的正应力δ和锚固体表面积A,从而提高锚索承载力的作用机理。该工艺在元磨高速公路K355,K356的滑坡治理中应用效果良好。
Introduce anchor cable for two times high-pressure splits grouting craft at the landslide strong decayed mudstone ＆ broccia, Raise completely soil body of C and ψ and shear slip surface ofnormal pressure δ and superficial area A for anchor from the macroscopic and tiny. Thus raise bearing capacity for anchor cable of action mechanism. That industrial art is in the Yuan-Mo Highway K355 and K356 of landslide manage the application result is good.
