| 摘 要： | 根据区划原则和方法,选择对公路选线,尤其对桥位选择及路基和桥涵水毁防治影响很大的河川径流强度作为中国公路水文二级区划指标.选择降雨、植被覆盖度、沟谷比重和河网密度作为河川径流强度的主要影响因素,建立了河川径流强度计算模型;综合考虑公路工程特点,提出了影响因素等级划分体系和影响度值;应用层次分析法得到各影响因素的权重值....

| Abstract: | According to the principles and methods of regionalization,river runoff intensity which has much restrict and influence on the highway route selection,especially on the selection of bridge site and prevention of water damage of roadbed and bridge was selected as the index of second-order hydrological regionalization for highway in China.The calculating model for river runoff intensity was built based on the main influencing factors like rainfall,vegetation coverage,gully proportion and drainage density.The ... |
