Abstract

Abstract:

During the construction of No. 5 and No. 6 bid sections of Nanchang Metro, ground surface settlement, gushing, water leakage and other incidents may occur. In the paper, the countermeasures taken to cope with the ground surface settlement, gushing, water leakage, and direction deviation etc. are presented. 

Key words: old urban area in Nanchang, ground surface settlement control, heterogeneous ground, gushing control, sand/water leakage at tunnel portal

CLC Number:

U 455
