摘要
预应力锚索加固技术在边坡工程中具有十分广泛的应用。本文以石门坎水电站边坡为例,运用强度折减法数值计算,得出预应力锚索加固前后边坡的安全系数。计算结果表明,预应力锚索支护可以通过改变潜在滑面位置和形状,提高边坡安全系数,进而提升边坡稳定性。
Prestressed anchor cable reinforcement technique is widely used in slope engineering. Hydropower Station slope is adopted as an example. Strength reduction method is adopted slope before and after the reinforcement of prestressed anchor cables. The calculation results show that the prestressedanchor cable support can improve the slope safety factor through changing the potential sliding surface position and shape,thereby enhancing the purpose of slope stability.
