河道格宾石笼护坡破坏模式及稳定分析

Failure Mode and Stability Analysis of Gabion Slope Protection in River Course

对格宾石笼护坡的工作原理、受力特点、破坏机理进行全面分析,总结出“沿石笼与土体接触面滑动破坏模式”、“沿土体内滑动面、石笼与土体接触面、河床土体滑动面滑动破坏模式”、“沿两层石笼之间滑动面滑动破坏模式”、“沿石笼外缘倾覆破坏模式”、“深层整体滑动破坏模式”等5种类型,优化了各种破坏模式稳定计算方法,为格宾石笼护坡设计提供依据和参考。

The working principle,mechanical characteristics and failure mechanism of Gabion slope protection are comprehensively analyzed and five types of failure modes are summarized such as“sliding failure modes along the contact surface between the Gabion and the soil”,“sliding failure modes along the contact surfaces such as slip surface in the soil,surface between Gabion and soil and bed slip surface”,“sliding failure modes along the interface between two-layer Gabion”,“sliding Failure mode of overturning along the outer edge of Gabion”,“sliding failure modes deep integral sliding”,etc.The stability calculation methods of various failure modes are improved and optimized to provide basis and reference for slope protection design of Gabion Gabion.
