四川康定母猪笼沟泥石流形成特征与物源定量计算
|
摘要
母猪笼泥石流的形成条件、受控因素和变化发展趋势在康定地区及周边具有代表性。通过调查,母猪笼沟形成区两岸滑坡体较大,主要为6个滑坡体和3个沼泽淤积土,边坡稳定性较差,在强降雨、饱水以及地震情况下,失稳可能性较大。综合分析,母猪笼沟松散物总储量达268050 m3,强活动物源(一次泥石流最大可能提供的物源量)储量达22550 m3。从水源、地形、物源补给、人工活动方面上,母猪笼沟泥石流处于活跃阶段,发生泥石流的可能性较大。
Sow cage debris flow formation conditions,the development trend of the controlled factors and changes in and around the region in Kangding representative.Through investigation,the two sides sow cage groove-forming region larger landslides,landslides of six major and three marsh sediment soil,slope stability is poor,the heavy rainfall,saturated with water and seismic cases,the possibility of instability the larger.Comprehensive analysis of the total sow cage groove loose material reserves of 268050 m3,a strong source of live animals(a landslide material source to provide the maximum possible amount) reserves of 22550 m3.From the water,topography,source material supply,labor activities,and sow the cage debris flow in the active phase,the occurrence of landslides more likely.
