| 摘 要： | 采用泰沙基折减自重模型,通过实例分别计算和分析了考虑内聚力和不考虑内聚力两种情况下的隧道竖向荷载大小及其与埋深的关系曲线,并与现场围岩压力测试结果进行比较,表明实测的隧道围岩最大压力值与模型计算结果相近,说明该模型适用于隧道围岩软弱破碎、风化不均的围岩压力的确定,从而为类似工程提供了借鉴。 |

| Abstract: | This paper uses Terzaghi reduction weight model to calculate the overlying loads of the tunnel and also the curves between the vertical load and depth of tunnel,by taking into consideration the cohesive and not taking into consideration the cohesive.Field measurement of rock mass pressure finds that the Terzaghi reduction model which takes into consideration the rock arch membrane effect achieves good results in Jiepaiguan tunnel.It is applicable to weak,weathered and broken surrounding rock,and could provi... |
