摘要
国道209线吕梁新城区段公路对缓减吕梁市区交通压力、保护横泉水库水源地、拓展吕梁市区及方山县的城市发展空间、打造宜居城市具有重要意义。为了保证国道209线吕梁新城区段公路改线工程按时保质完成、爆破设计和爆破施工不出错,本文介绍了该工程的地质条件,阐述了该工程隧道爆破设计技术要求及设计原则,详细讨论了该工程隧道爆破参数、施工工艺、安全措施,指出与以往隧道爆破施工工程相比,该工程开掘出了更多爆破施工的自由面,改善了隧道爆破施工效果,有利于加快施工进程,达到了快速作业要求和安全施工要求。
Lyuliang new urban section of National Highway 209 is of great significance to alleviate the traffic pressure in Lyuliang City, to protect the water source of Hengquan Reservoir, to expand the urban development space of Lyuliang City and Fangshan County, and to create a livable city. In order to ensure that the highway reconstruction project of Lyuliang new urban section of national highway 209 is completed on time and with good quality, and the blasting design and construction are not wrong, the geological conditions of the project are introduced, the technical requirements and design principles of the tunnel blasting design are elaborated, and the tunnel blasting parameters, construction technology and safety measures of the project are discussed in detail. It is pointed out that compared with the previous tunnel blasting construction projects, more blasting construction free surfaces are excavated, the tunnel blasting construction effect is improved, and the construction process is accelerated to meet the requirements of fast operation and safe construction.
