An Elementary Introduction to Soft Layered Surrounding Rock Support at the Intersection of Inclined Shaft and Main Tunnel in Large Railway Tunnel;

This paper introduces the general situation and geological conditions of Wenyuhe Reservoir,and expounds the procedures and results analysis of the middle-sized shear test on the rock in weak interlayer of Wenyuhe Reservoir.

This paper synthetically analyzed various data about weakly consolidated sand formation, and established theoretical models and methods studying on the sand production mechanism and analyzing the sand production trend for weakly consolidated sand formation qualitatively and quantitatively, which employ logging information as support, and are based on rock mechanics fundamental theories.
