简述公路隧道衬砌式样分析与支护技术

On analysis of lining styles of roads and tunnels and its support technique

对公路隧道工程中喷锚衬砌、整体式衬砌以及复合式衬砌三种衬砌式样进行了分析,基于围岩特性的不同,提出了相应的支护形式,并对钢架支护形式、喷射混凝土支护形式、锚杆支护形式作了阐述,以供参考。

The paper analyzes the three lining styles, that is, shorcrete boh lining, integrated lining and composite lining, in the roads and tun- nels projects, points out respective support forms based on various surrounding rock features, and illustrates the rigid-frame support, sprayed concrete support, and anchor bolt support, so as to provide some reference.
