| 摘 要： | 根据川藏公路培龙沟１９８３～１９８５年的泥石流活动，分析了支沟泥石流的输砂才江成因，揭示了堵江现象主要与支干流汇流关系，干流段地貌条件、干流洪水水动力条件、支沟泥石流性质和泥石流规模有关，并通过各相关因素的分析，提出了支沟泥石流输砂堵江的判别准则。

| Abstract: | The study is based on the activities of debris flow in Peilonggou gully in the Sichuan-Xizang highway during 1983 - 1985. The main river(Palongzangbu River) is blocked by the debris flow from the branch gully(Peilonggou Gully ). This is caused by the following factors: the relationship between main river and the branch, the landform of main river, hydrodynamic condition of flood of main river, the property and dimensions of debris flow in the branch. Analyzing the relative factors, the discrimination model for blocking is presented. |
