Integrated Survey and Route Optimization of Railway Line Passing through Small Goaf
In the region with complex geological condition,it is important to carry out geological route selection for railway engineering.In this paper,a railway line passing through a small goaf was taken as an example.Under the condition that the line was unable to bypass the small goaf,the means of integrated survey was used to survey the goaf.First,on the basis of the initial geological mapping,the geophysical prospecting method was used with targeted prospecting lines,and then the geological drilling was arranged to perfect the information of the goaf prospected.Afterwards,through comprehensive analysis on survey data,the detailed scope and scale of the goaf was mapped out,and the route scheme was adjusted and optimized.Practice of construction shows that the means of integrated survey is useful for optimizing the route.
