摘　　要：在《公路工程建设项目概算预算编制办法》(JTG 3830-2018)中,隧道洞身土石方开挖、超前小导管、初期支护、二次衬砌、隧道防排水等造价没有按照围岩等级分别计列,只是按照长度笼统计算出隧道的综合造价指标,无法准确反映不同围岩等级对隧道综合造价指标的影响,隧道综合造价指标差异较大,这使得上级审批部门无法准确控制隧道工程造价。为了掌握不同围岩等级的隧道造价情况,本文根据云南省某高速公路隧道设计资料,对隧道工程不同级别围岩的造价进行了详细的分析探讨。In the"Method for Budgeting of Highway Engineering Construction Projects"(JTG 3830-2018),the costs of tunnel excavation,small pipe-roof protection,initial support,secondary lining,tunnel waterproofing and drainage,etc.are not separately calculated according to the surrounding rock classification.The comprehensive cost index of the tunnel is only calculated based on the length,which cannot accurately reflect the impact of different rock classification on the comprehensive cost index of the tunnel.The comprehensive cost index of the tunnel varies greatly,which makes it difficult for the approval department to accurately control the cost of the tunnel project.In order to understand the cost of tunnels with different classes of surrounding rock,this article conducted a detailed analysis and discussion on the cost of tunnels with different classes of surrounding rock based on the design data of a tunnel on a expressway in Yunnan province.
