摘要
自上世纪50年代以来,中国企业开始研究隧道掘进机技术,经历了自主探索、技术引进和自主创新的历程.如今,中国已经具备了设计、制造多种类型隧道掘进机的技术创新能力.中国企业成功研制出了混合模式掘进机、异形断面掘进机、联络通道掘进机、竖井掘进机、斜井掘进机等多种新设备.中国的隧道掘进机技术水平总体上达到国际先进水平,并在新型破岩技术研究和新机型研发方面引领了行业的发展.未来,隧道掘进机技术的发展可以从"三个层次、一个提升"的角度进行探讨,包括在现有掘进机技术框架下,通过完善设备功能和提升性能来提高技术水平;突破破岩技术,并创新地下支护结构,推动新型隧道掘进机的发展;随着隧道理念的变化,推动隧道掘进技术的进步.同时,隧道智能化建设也需要得到提升,以提高施工效率和安全性.
Abstract
Since the 1950s,Chinese enterprises have commenced research on tunnel boring machine technology,tra-versing a journey from independent exploration and technological import to indigenous innovation.Today,China has attained the capability for technological innovation in designing and manufacturing various types of tunnel boring machines.Chinese enterprises have successfully developed an array of new equipment,including mixed-mode boring machines,irregular cross-section boring machines,connection passage boring machines,vertical and inclined shaft boring machines,etc.The overall technology level of China's tunnel boring machines has reached the international advanced standard,leading the industry in the research of new rock-breaking technologies and the development of new models.The future development of tunnel boring machine technology in China can be explored from the per-spective of"three levels and one enhancement,"which includes improving the technological level under the existing framework of boring machine technology through improving the function and performance of the equipment;breaking through in rock-breaking technology and innovating underground support structures to promote the development of new tunnel boring machine;and advancing tunnel boring technology progress in response to evolving tunnel con-cepts.Concurrently,the enhancement of intelligent tunnel construction is necessary to boost construction efficiency and safety.
