超大直径土压平衡盾构土舱压力和开挖面水土压力分布特性研究
Study of distribution properties of water and earth pressure at excavation face and in chamber of earth pressure balance shield with super-large diameter
摘要
Abstract
The chamber pressure control is a key operation for controlling the impact of the earth pressure balance (EPB) shield excavation on the environment. Based on the monitored data, the water and earth pressure distribution properties in chamber and at the excavation face of a super-huge diameter EPB shield tunneling are studied. According to the construction parameters analysis, it is found that the increment of chamber pressure could be calculated by the construction parameters, such as rotation speed of screw conveyor and advancement rate. In addition, the water and earth pressure at excavation face could not be transfer to the chamber completely, and the transmissibility is about 76.3%. The research results of this paper provide valuable references for the setting method of the chamber pressure of the super-huge diameter EPB shield.关键词
