摘要:
在我国发生的众多滑坡灾害中,最为突出的一个致灾因素是降雨。针对降雨诱发滑坡的研究一般是将边坡失稳的机制作为着手点,研究湿润锋向下发展的运移规律。针对Mein-Larson降雨入渗模型在模拟水分入渗过程中未充分考虑初始含水率分布的非线性这一不足,引入考虑初始含水率分布的非线性即指数分布进行土体含水率分布、土体累计入渗雨量的修正,并进行改进Mein-Larson降雨入渗模型的研究,通过试验验证了改进之后的降雨入渗模型的正确性与合理性。
Abstract:
Among the many landslide disasters in China, the most prominent disaster causing factor is rainfall. The research on rainfall-induced landslide generally takes the mechanism of slope instability as the starting point to study the migration law of the downward development of wetting front. Aiming at the deficiency that the nonlinearity of the initial water content distribution is not fully considered in the simulation of water infiltration process of the Mein Larson rainfall infiltration model, this paper introduces the nonlinearity of the initial water content distribution,that is,the exponential distribution,to correct the soil water content distribution and the cumulative infiltration rainfall of the soil, and studies the improved Mein-Larson rainfall infiltration model. The correctness and rationality of the improved rainfall infiltration model are verified by experiments.
