青藏线扎麻隆——岳家村区段所处的山区是西北地区暴雨型泥石流发育较为典型的地区之一,分布有21条泥石流沟,其中西岭台沟是这一地区中对铁路构成严重危害的一条泥石流沟。 西岭台沟泥石流之所以形成,主要与其自然条件及人类经济活动相关。其地质地形条件是发生泥石流的内在因素,而水的作用及开山修渠弃碴则是激发条件。本文对该沟产生泥石流的诸因素做出初步分析,并对运营部门防治泥石流灾害提出治理建议。
The mountainous area where Zhamelong-Yuejiacun section of Qinghai-Tibet Railway is located is one of the typical areas where rainstorm-type debris flow develops in Northwest China. There are 21 debris flow ditches distributed, of which Xilingtougou is a severe railway in this area A debris flow hazard ditch. The formation of Xiling Ridge Mudflow is mainly related to its natural conditions and human economic activities. The geological and terrain conditions are the intrinsic factors of debris flow, and the role of water and repair ditches is the excitation conditions. This paper makes a preliminary analysis of the factors that cause the debris flow in the ditch and puts forward some suggestions for the prevention and control of the debris flow disaster in the operating department.
