Slope anchor cable reinforcing new Austrian method
The invention provides a new Austrian method for reinforcing a side slope by adopting an anchor cable, and a method for calculating generalized residual shear strength in the new Austrian method for reinforcing the side slope by adopting the anchor cable is established; the optimal matching design scheme between the side slope and the anchor cable can be found out, the design is reasonable, and construction is convenient. Firstly, a sliding surface residual thrust distribution curve is determined through a generalized residual thrust method, the residual shear resistance value of each strip block of a sliding body is determined, anchor cables are designed at the positions where the residual shear strength reaches or approaches the allowable shear strength under the certain safety reserve condition, the residual shear resistance of a rock-soil body is within the allowable shear strength range, and the residual shear resistance value of the rock-soil body is determined. When the shearing resistance of each block of the side slope reaches or approaches the allowable shearing resistance, the anchor cables are additionally arranged, so that the shearing resistance of the rock-soil body is fully exerted, the rock-soil body is prevented from being damaged by shearing, the gliding force of the side slope body is jointly borne by the rock-soil body and the anchor cables, and the residual gliding force curve of the side slope is in a horizontal fluctuation form. And moreover, the safety of slope engineering is ensured under an allowable shear strength curve of the rock-soil body.
本发明提出了采用锚索加固边坡的新奥法，建立了边坡锚索加固新奥法中广义剩余抗剪强度的计算方法；通过本发明可以找出边坡与锚索之间的最佳匹配设计方案，其设计合理且施工便利。首先通过广义剩余推力法确定滑动面剩余推力分布曲线，确定滑体每个条块的剩余抗剪力数值，在有一定安全储备条件下剩余抗剪强度达到或接近允许抗剪强度的位置处设计锚索，使得岩土体的剩余抗剪力在允许抗剪强度范围内，当边坡各条块抗剪力达到或接近允许抗剪强度时增设锚索，由此不仅充分发挥了岩土体的抗剪强度，又保证岩土体不会被剪切破坏，边坡体的下滑力由岩土体与锚索共同承担，使得边坡的剩余下滑力曲线呈现水平波动形式，且分布岩土体的允许抗剪强度曲线之下，确保边坡工程的安全性。
