| Abstract: | In dealing with the abnormal abrasion happened to the tools of the large-diameter slurry shield machines in Nanjing Yangtze River Tunnel when passing through gravel-sand cobble stratums,an improvement proposal is put forward from aspects of tool design and processing. The construction application shows that the service life of improved tools is six times of original ones,which could be taken as reference for similar projects. |
