摘要:
南水北调西线一期工程区是我国水能资源最为丰富的地区之一，在该区修建水利工程，泥石流是经常遇到的地质灾害问题。在考察论证的基础上，结合工程区泥石流发育与地质构造、地层岩性、气象水文和地形地貌的关系，探讨了泥石流分布规律。研究表明，工程区泥石流沟数量较多，但分布不均匀；泥石流沟流域面积集中于1~5 km2，主沟长度以1~3 km居多，相对高差大多小于1 500 m；70.9%的沟谷坡度为10~30°，88.3%的沟床比降在0.1~0.5之间；泥石流分布受地形地貌的控制，受地质构造和地震的制约，受地层岩性的影响，表现出区域分异的特征。
Abstract:
The area of the 1st stage project of west-line for diverting water from southern to northern China is an area where is rich in hydro-energy resource in China.However,debris flows are the main geological hazards threatening the project construction.Based on field investigation,the distribution of debris flows in the project region is discussed.The following results show:the number of debris flow gullies is large,but their distribution is not even;most debris flow catchment areas are among 1 and 5 km2;most of the main gully length are between 1 000 and(3 000 m);the altitude of the gully mouth is within(3 000) and 4 000 m,and relative altitude is less than 1 500 m;most slope gradients are between 10° and 30°,and most gully bed ratio is in 0.3 to 0.5;differences of hydro-thermal conditions related to slope lead to different distribution of debris flows;the debris flow distribution is controlled by the geological structures,earthquake,lithology and landform,and it has regional differential rule.
