The adaptability analysis of cutter tool to slurry shield of Beijing railway underground diameter line

He Feng,Li Xiaogang,Sun Shanhui

Strategic Study of CAE 2010, Volume 12, Issue 12,   Pages 35-40

Abstract:

Based on the underground diameter line engineering experience from Beijing railway station to Beijing railway west station, through the application contrast of various cutter tool configurations under sandy gravel, a detailed comparative analysis of cutter tool adaptability was done focusing before and after transformation. The key issues were proposed about cutter tool configuration under sandy gravel, which can be reference to similar projects.
