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。 By introducing the two concepts of maximum incidence ray and angle of expectation of the anchored linear landslide anchorage structure, the stress of the anchored landslide anchoring structure is calculated. Using the expected angle instead of the dip angle of the whole polyline, the calculation of the stress of the broken line landslide can be transformed into the force calculation of the linear landslide anchoring structure. The example shows that this method obviously simplifies the stress calculation process of the anchored structure of the zigzag landslide, and provides a reference for the design of the anchorage support of the zigzag landslide.
