近年来,国民经济长足发展,为满足工业生产、城镇居民生活用水及城市综合市政应用的需要,大跨度的引水及城市综合管廊工程得到了较大的发展。这类工程的共同特点就是地质较为复杂,且隧洞断面小。如何有效控制隧洞的开挖质量,值得探讨研究。本文以山西引黄水利工程隧洞开挖爆破施工为例进行总结,希望对类似工程施工者能提供一定帮助。
In recent years, due to the rapid development of the national economy, in order to meet the needs of industrial production, domestic water for urban residents and the application of integrated urban administration in cities, the long-span diversion project and urban integrated pipe gallery project have made great progress. The common feature of such projects is that the geology is more complicated and the tunnel section is small. How to effectively control the quality of tunnel excavation is worth discussing. In this paper, Shanxi Yellow River Water Conservancy Project tunnel excavation blasting construction as an example to summarize, hoping to provide some help to similar project builders.
