Other AbstractBeam dam,as one of the most important and common open-type check dams in debris flow control projects,has good application prospects and value in debris flow control for railway lines.The regulating effect of beam dam on debris flows,is mainly reflected in these aspects,such as bulk density,peak discharge,total volume,impact characteristics and duration of debris flow.Based on the principle of dimensional analysis,a formula for determining regulative performance of beam dam considering the effects of debris flow properties, structure parameter of beam dam and fluid motion state was deduced.Combined with the indoor flume simulation test results,the corresponding coefficients in the calculation formula were determined by the least square method,and the calculated values are consistent with the experimental values.The research results can provide reasonable basis and technical support for the optimized design of beam dam,and are conducive to the objective evaluation of the regulative effect of beam dam,in order to make a better role of the beam dam in disaster prevention and mitigation.
