Abstract:

Based on the practice of shield construction in Bid 2 of Chengdu Metro Line 1, a study is made on the excavation face balance and stability of fine sand layer bored by S-366 shield machine. An exemplary calculation of the establishment of two balance modes of EPB shield machine crossing through single stratum is made and a discussion is made to the 2 balance modes.

Key words: EPB shield machine, fine sand layer, failure mechanism, balance mode
