泥石流现象多发生在条件具备的山区,暴发突然,发生的准确时间很难预知,因此将中心点三角白化权函数法运用于硬梁包水电站左岸磨子沟泥石流易发性评价中。将所在地的观测指标划分为若干个可定义的类别,从而对泥石流易发性进行评估,得出评估结果为轻度易发,并将其与基于端点三角白化权函数的评估结果和实际情况进行比较,两者评价结果一致,而前者的评估过程更加科学合理并且与当地实际完全相符,从而在此评价基础上采取建设性措施对该地泥石流沟进行了排导和防护。
泥石流現象多髮生在條件具備的山區,暴髮突然,髮生的準確時間很難預知,因此將中心點三角白化權函數法運用于硬樑包水電站左岸磨子溝泥石流易髮性評價中。將所在地的觀測指標劃分為若榦箇可定義的類彆,從而對泥石流易髮性進行評估,得齣評估結果為輕度易髮,併將其與基于耑點三角白化權函數的評估結果和實際情況進行比較,兩者評價結果一緻,而前者的評估過程更加科學閤理併且與噹地實際完全相符,從而在此評價基礎上採取建設性措施對該地泥石流溝進行瞭排導和防護。

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.
