| The value of surrounding rock pressure in foundation base zone of loess tunnel has a direct influence on whether the tunnel base bearing capacity meet the requirement of structural stability and operation safety. This article takes the loess tunnel as the research object, uses Platts theory, Terzaghi theory, Xie Jiaxiu theory, Bill bauman theory, Caquot theory, soil column method, rock pillars method, code method, and finite element method to compare and analyze measured values, and recommends that losee tunnel should use Terzaghi theory and finite element method to calculate pressure of surrounding rock. |
