某泥石流缝隙坝设计及计算分析

某泥石流沟物源丰富，采用缝隙坝可以有效地拦挡块体物源，起到拦挡节流和稳固沟床的作用。根据现场分析，确定在泥石流主沟下游设置缝隙坝，计算了泥石流缝隙坝自重、动水压力、竖向压力、扬压力、水平水压力、水平土压力、泥石流整体冲击力和石块冲击力等，对缝隙坝的抗滑移、抗倾覆、地基稳定性进行了验算，验算结果表明该泥石流缝隙坝满足设计要求。

Design,Calculation and Analysis of the Slit Dam of a Debris Flow

In the debris flow with abundant debris source, the slit dam can effectively reduce block source and reinforcement the solid bed. According to the field analysis, a slit dam will be set up at the bottom of the main ditch. The gravity, dynamic water pressure, vertical pressure, uplift pressure, horizontal water pressure, horizontal earth pressure, overall impact force of debris flow and rock mass impact are calculated. The anti-slide, anti-overturning and foundation stability of the dam are checked. The results show that the dam meets the design requirements.
