深埋山岭隧道帷幕注浆段衬砌外水压力研究
Study on External Water Pressure of Lining in Curtain Grouting Section of Deep-buried Tunnel
摘要
Abstract
The flow model of deep-buried tunnel is established in this paper to analyze the influence of the external water pressure on the load of supporting system. The two calculation formulas, water pressure on the outer lining structure and the equation of maximum water inflow, are derived from theoretical analysis. On the basis of the obtained equations, this paper addresses the applicability of these equations to the actual tunnel construction. The external water pressure on the outer lining structure is monitored in the curtain grouting section of Taihang Mountain. The monitoring results indicate that though the water pressure on outer lining structure in curtain grouting section is small, continuous monitoring of external water pressure in rich water sections must be reinforced in view of the future increase of water pressure and the safety of tunnel service.关键词
