路基局部冲刷深度研究进展

Development of Research on Local Scour Depth of Subgrade

沿河路基冲刷是公路水毁的一个重要类型,而最大冲刷深度将直接影响沿河路基的安全。在对沿河路基局部冲刷机理的分析基础上,综合各家局部冲刷深度公式,评述其优缺点,指出现在存在的诸多问题。

Scour of subgrade along river bank is a main type of highway washout by flood. The maximum scour depth would affect the subgrade safety directly. Based on mechanism analysis of local scour of subgrade, this paper analyzes the local scour depth formulae and points out the problems which should be solved in the future.
