国内外非粘性土桥墩局部冲刷计算方法综述

Synthetical Review of Calculation Methods for Non -clay Local Scour Around Bridge Pier

本文总结了国内外非粘性土桥墩局部冲刷的计算方法。国外众多计算方法在国内使用中有其局限性。国内计算方法主要以６５－１式为主，近年来，在６５－１式基础上又出现一些改进的计算方法，使得计算方法更趋于合理。对多沙细沙河流，张红武公式形式较为简捷。

In this paper , the calculation methods for non-clay local scour around pier have been sumed up. The methods used in other countries have limit in China. In China the 65- 1 formula is a common method , and Zhanghongwu formula is batter for much fine sediment river.
