基于成渝客运专线新红岩隧道的数码电子雷管爆破定额测定与费用分析

Quota Determination and Cost Analysis of Digital Electronic Detonator Blasting of the New Hongyan Tunnel in Chengdu-Chongqing passenger Dedicated Line

为确保铁路隧道工程施工进度和安全,研究城市区域隧道的控制爆破施工技术十分重要。此文以成渝客运专线新红岩隧道工程施工为依托,在阐述采用数码雷管爆破施工流程和技术要点的基础上,采用写实记录法对数码雷管爆破施工定额进行测定与分析。并对IV级和V级围岩下数码雷管控制爆破施工基价进行分析。

In order to ensure the construction progress and safety of railway tunnel, it is very important to study the construction technology of controlled blasting for urban area tunnels. Based on the construction of the new Hongyan tunnel in Chengdu - Chongqing passenger dedicated line, the construction process and technical essential of digital electronic detonator blasting are expounded. The construction quota is measured and analyzed using realistic record method. And the base price of digital electronic detonator controlled blas- ting of IV and V class surrounding rock is analyzed.
