| 摘 要： | 偏压是隧道洞口段施工经常遇到的情况，给施工带来极大的困难。统计分析造成隧道偏压的原因，针对某高速公路隧道偏压段，应用数值模拟和现场监测分析其安全性。结果表明：造成隧道偏压的因素有地形因素、地质因素和工程因素；围岩变形和支护结构受力均能满足要求，现场地表沉降的监测值也较小。

| Abstract: | Unsymmetrical press is often common in tunnel entrance section,which brings great difficulties to the construction.The factors causing unsymmetrical pressure were firstly analyzed,and for a unsymmetrical tunnel,numerical simulation and field monitoring were used to analyze of their safety.The results showed that:the factors causing unsymmetrical pressure is terrain,geology and construction;rock deformation and internal force of supporting structures can meet the requirements,on-site monitoring of ground val... |
