Risk analysis on cutter head failure of shield in composite ground
All kinds of accident examples and their potential reasons were analyzed and summarized for cutter head failure of shield in composite ground. In order to research the mechanism of failure risk mode on cutter head, cutters and other different cutting components in shield, Fault tree analysis (FTA) was applied in establishing an analytical model on cutter head failure risk. Firstly, potential failure risk modes and effect factors were all analyzed and calculated by set theory in a qualitative way. Then, relevant control measures were proposed to reduce the cutter head failure risk of shield. The paper results would give some useful references for cutter head design and construction in composite ground by shield in China.
