输电线路溃堤洪水冲刷计算方法研究

摘要

According to the analysis of the existing dike break scour calculation method, the equivalent diameter of soil scour directly affects the calculating results. For the same reality, subjective factors of the different designers lead to the differences of soil equivalent diameter. The layer-by-layer trial calculation method can effectively avoid the error, which generated by the subjective consciousness of designers. This method can avoid the investment waste and the security risk.%现有的溃堤洪水冲刷计算方法中，土壤当量直径的选择直接影响洪水冲刷计算的结果。而面对相同的地质条件，不同设计人员的主观因素可能导致土壤当量直径选取存在差异。采用逐层试算法进行计算，可以有效的降低由于设计人员的主观因素带来的误差，从而避免浪费投资或造成安全隐患。
