在野外现场调查和理论分析的基础上,考虑降雨量的损失和降雨作用的滞后性,提出了有效降雨量的计算方法;通过有效降雨量的统计分析,确定了砂黄土地区以及典型黄土地区公路边坡可能发生失稳破坏的有效降雨量分级值即雨量线值,并用雨量线方法进行公路边坡失稳预测.通过工程实例验证,表明雨量线法具有较好的实用性.

Based on field investigation and theoretical analysis, this paper puts forward the model of calculating effective rainfall, considering the loss and posteriority of rainfall.After statistical analysis of effective rainfall, the grading scores of effective rainfall line in loess area for highway slopes where the possibility of unstable failure may be exist have been determined.Finally, engineering application validates that the rainfall lines work on the instability prediction for highway slope effectively, which may find its wide application in loess area for the prediction and forewarning of highway slope rainfall hazard.
