Abstract:

Gravity analysis for the first-wall of CH HCSB TBM shows that the stress and displacement of first-wall caused by the gravity effect are too small and could be ignored. And the results of thermal-mechanical analysis for the first-wall show that the stress of Be armor is higher than allowable vaue, so it’s proposed to choice W/Cu alloy replaced Be as the armor of first-wall under considering the point of structure design.
