Abstract

Abstract:

Jiangbeicheng station is a mined large span station on No.6 line of Chongqing rail transit system. There is 9 190 337 Yuan economic losses caused by the big collapse happened during the construction of this station, though no casualty is leaded. In this paper, the construction method for Jiangbeicheng station is introduced first. And then the direct and indirect causes of the collapse are analyzed and the prevention measures are proposed for the similar construction condition.

Key words: rail transit system, mined large span station, collapse
