泥石流斜墙式V型排导槽的设计分析

Analysis of V-shaped slope wall drainage channel in debris flow

针对泥石流斜墙式V型排导槽的水力最佳断面和槽底的内力计算问题,基于水力学理论和链杆法,分别推导其计算公式。结果表明:该类槽型的水力最佳断面与深度无关,用链杆法计算槽底内力更为简便。最后,以平川泥石流为例,进行了排导槽槽底的内力计算。

In order to solve the problems about the optimal hydraulic section and the internal force of the bottom of V - shaped slope wall drainage channel, based on the theories of hydraulics and rigid bar method, the calculating methods for them have been put forward. The results show that the optimal hydraulic section has nothing to do with the depth, and it is more convenient to calculate the internal force of the bottom of V - shaped slope wall drainage channel by rigid bar method. At last, the rigid bar method has been carried out in the case of Pingchuan debris flow to calculate the internal force of the bottom of V - shaped slope wall drainage channel.
