摘要:

以某长大公路隧道为工程背景,采用现场测试方法,对软弱破碎围岩条件下,隧道初期支护的受力特征进行了具体分析。重点探讨了工字钢支撑、喷射混凝土的受力及围岩压力的变化规律和分布大小,为类似条件下隧道支护设计和安全施工提供科学依据和技术指导。

Abstract:

Taking a long road tunnel for engineering background,by the in-situ test method,the mechanic characteristics of tunnel initial support in weak-broken surrounding rock are analyzed concretly.The change law and size distribution of force acting on the joist steel support and shotcrete and surrounding rock pressure are discussed mainly,which can provide scientific basis and technical guidance for tunnel design and construction safely under the similar conditions.
