定性地分析了极端气候事件对膨胀土路基水毁的影响,指出日降雨极值和干旱持续时间是影响膨胀土路基水毁的极端气候事件。定量地计算了不同重现期的日降雨极值和不同干旱级别的干旱持续时间对膨胀土路基水毁的影响。
The effect of extreme climate events on expansive soil roadbed water - destroyed was analyzed. The effect of maximum value of daily rainfall in different return periods and the different drought durations to expansive soil roadbed water - destroyed were calculated quantitatively. The analysis results show that the maximum value of daily rainfall and drought duration are the extreme climate events which affects the expansive soil road- bed water - destroyed.
