Abstract

Cutter wear is an important factor that restricts construction efficiency and cost in TBM tunneling, and abnormal cutter damage will even cause TBM jamming, seriously affecting the construction schedule. Therefore, using PFC particles flow numerical simulation method, two simulation schemes which will possibly cause cutter abnormal damage are set up, researching the mechanics behavior and efficiency of rock breaking. Otherwise, the influence of penetration, rock mass strength and parameters of the cutter itself on cutter force is also analyzed, and the corresponding engineering suggestions are provided in this article.
