叶城县泥石流防治工程拦砂坝设计分析

Design and Analysis of Sand Bar for Debris Flow Control Project in Yecheng County

拦砂坝,是在沟道中以拦蓄山洪及泥石流中固体物质为主要目的的拦挡建筑物.拦砂坝在泥石流防治工程中可以拦蓄山洪或泥石流中的泥沙(包括块石),减轻对下游的危害.论文通过阐述新疆叶城县泥石流灾害发展分析、防治工程的设计指标,重点介绍了拦砂坝的设计、计算及在防治工程中起到的作用,可为类似泥石流防治工程中拦砂坝的设计与应用起到参考作用.

Sand bar is a kind of block structure in gully with the main purpose of retaining the solid material in mountain flood and debris flow.Sand bar in debris flow control engineering can play a role in the retention of mountain flood or debris flow sediment(including rocks),reduce the harm to the downstream.This paper expounds the design index of the debris flow disaster development analysis and control project in Yecheng county,Xinjiang province,and mainly introduces the design,calculation and function of the sand bar in the control project,which can play a reference role in the design and application of the sand bar in similar debris flow prevention project.
