成昆铁路沿线所经地区,地质构造极为复杂,是我国铁路经常遭受泥石流袭击的一条重要干线。 为了根治成昆铁路泥石流病害,弄清沿线泥石流的形成规律。笔者对成昆铁路铁西～沙木拉达段陆地卫星MSS图象进行了判释、编制出1:20万地质构造判释图,并运用地质力学观点对该段泥石流发生发展的构造地质条件进行了初步分析。
The area along the Chengdu-Kunming Railway has an extremely complicated geological structure and is an important trunk line to which our country’s railways are often subjected to debris flow attacks. In order to cure the landslide disease in Cheng-Kun Railway, we can understand the formation of debris flow along the route. The authors interpreted the MSS image of the land satellite from Chengxi-Shamu Ladda of the Cheng-Kun Railway, and developed a 1: 200,000 geologic tectonic interpretation map and applied the geomechanical point of view to analyze the tectonic and geological conditions Conducted a preliminary analysis.
