汛期土质边坡的坍塌不但与边坡土体的工程地质条件因素有关,还与降雨因素(降雨持续时间,降雨强度大小等)有着极为密切的关系;而且在一场降雨中,对边坡的稳定性起作用的是实际入渗到土体中的那一部分雨量。所以,在人们试图以一场连续降雨量的大小作为土质边坡坍塌的预测指标时,这部分雨量的计算处理是至关重要的。从理论上讲,若能将各土体的入渗规律弄清,并将一场降雨中真正入渗至土体中的水量
The collapse of soil slope in flood season is not only related to engineering geological conditions of slope soil, but also closely related to rainfall factors (duration of rainfall, intensity of rainfall intensity, etc.). In a rainfall, Stability plays a part in the amount of rainfall that actually infiltrates into the soil. Therefore, the calculation of this part of the rainfall is of crucial importance when one tries to predict the extent of the collapse of a soil slope with a continuous rainfall. In theory, if we can clarify the law of infiltration of soil, and a real infiltration of water into the soil in the rainfall
