| 摘 要： | 引入折线形滑坡锚固结构的最大概然入射线、期望角两个概念,来计算折线形滑坡锚固结构的受力情况。用期望角代替整个折线形滑面的倾角,可以将折线形滑坡锚固受力计算转变为直线形滑坡锚固结构的受力计算。实例表明,该法明显简化了折线形滑坡的锚固结构受力计算流程,可为折线形滑坡的锚固支护设计提供参考。

| Abstract: | Maximum-probability incident line and expected incident angles are introduced to calculate the anchoring force of mansard landslides.With the expected incident angle replacing the dip angle formed by irregular sliding surfaces,the calculation of the landslide anchoring force is transformed into the calculation of straight lines from that of irregular lines.Examples show that the above method simplifies the calculation of anchoring force,shedding light on the design of anchoring support for this kind of landslide. |
