Abstract
Debris flow often occurs in the mountain area w ith ripe conditions, and its sudden outbreak makes it difficult to predict the exact occurrence time. In this paper, the triangle w hitening w eight function method of cent ral point w as applied to evaluat e the prone degree of the debris flow on the left bank of grind gully of the Yingliangbao hydropow er station. The observat ion in-dexes w ere divided into several def ined categories, w hich can assess the susceptibility of debris flow using the t riangle whitening weight function method of central point. The evaluation results show ed that prone degree of debris f low is mild in the study are-a. Compared w ith the results obt ained from the triangle whitening w eight function of endpoint, the triangle whitening w eight function method of central point met hod is more scientific and reasonable and fully consistent with the act ual conditions. On the basis, the constructive measures w ere proposed for the drainage and protection of the debris flow gully in the study area.关键词
