摘　　要：为促进液压凿岩台车开挖技术在长大铁路隧道建设中的推广应用和经济分析工作的开展,对液压凿岩台车开挖技术的应用和经济分析工作要点进行探讨,对液压凿岩台车开挖技术中的超挖成因和经济分析工作基础资料收集等关键问题进行阐述和分析。通过探讨分析可知,应用液压凿岩台车开挖技术建设长大铁路隧道,技术上是可行的,经济上是合理的。The key points of the application of and economical analysis on tunnel excavation by hydraulic rock drilling jumbos are discussed. The causes for the overbreak induced by hydraulic rock drilling jumbos and the collection of the basic data needed for economic analysis are presented and analyzed. The analysis results show that hydraulic rock drill- ing jumbos are suitable, rational and economical for the excavation of long railway tunnels.
