Study on the Adit Stability Under Dynamic Blasting Load;

This paper introduces the method for directive generation of adit graphic files with the information from multiple sources acquired during tunnel construction using MAPGIS component technology.

In combination with rock permeability in dam region of a hydroelectric plant,the paper introduces a method directly evaluating rock permeability coeffieient--adit sonic wave hole seepage test and gives test device,test procedure,estimate principle and result.

By investigating the soil salt content and groundwater quality of typical profiles of soil and water development regions in Fukang City and Hami City, this study analyzed the redistribution characteristics of salt content in soil and groundwater under conditions with or without horizontal drainage in the initial stages of reclamation.
