【摘要】 本文阐述了锚钉联合加固基坑边坡的支护机理 ,指出锚钉加固后的基坑边坡存在着整体失稳两种破坏方式。以上的塑性和极限分析理论为基础 ,通过把锚钉对基坑边坡的支护约束转化为能量的形式 ,本文从能量稳定的角度建立了锚钉联合加固基坑边坡的设计方法。最后 ,本文给出了该课题的具体设计算例更多还原

【Abstract】 In this paper it is pointed out that there are general and local failure existed in deep cuts reinforced by anchors and soil-nails,and the retouining mechanism is expounded. Based on theory of plastic limit analysis.about soil, the restraint of anchors and soil-nails is transformed into the toergy. The design method for deep pits retained by anchors and soilmnails is established ,a last,a practical example is preasented更多还原
