Determining on Rational Burial Depth of Subway Tunnel Based on Safety Factor
摘要
Abstract
How to determine the burial depth of subway tunnel based on economy and safety is one of the difficult problems of subway design. Taking the rational burial depth design of a subway tunnel in Qingdao as an example, the strength reduction method is applied to the analysis of tunnel rational burial depth. Safety factor of unlined hole is obtained by strength reduction method in different depth. Actual geological conditions are considered to safety factor of unlined hole in different burial depth. By using the change rule of safety factor, rational burial depth of subway tunnel can be determined through quantitative analysis.关键词
