摘　　要：TBM法隧道施工技术在我国已经得以大力推广,同时施工的TBM数量已达40余台(套),有TBM施工业绩的企业近20家。TBM法隧道施工规模的扩大,并未能带动整体施工水平的全面提升,TBM掘进施工速度差异巨大且不均衡已经成为较为显著的问题,导致工期延迟、成本增加,造成巨大的经济和社会效益损失。结合近20年的TBM施工实践,探索并实施SPS作业法,即TBM持续、均衡、快速施工技术,提出"3个基础""10项措施"实现适宜地质条件下TBM持续、均衡、快速施工;而在恶劣地质条件下,通过完善设备功能与性能、改进施工工艺,提升TBM工程适应性;从而促进TBM工法科学、可持续发展。The construction technology for TBM tunnel has been widely popularized in China.There are 40 sets of TBM working at the same time,and nearly 20 enterprises own the achievement of TBM construction.The number of tunnels constructed by TBMs has been expanded,but overall TBM construction level has not been promoted in an all-round way.The construction speed of TBM is very different and the imbalance has become a significant problem;which leads to the time delay,cost increase and huge economic and social loss.Therefore,the 20 years of TBM construction practice is introduced,the sustained,proportional and speedy(SPS)construction method has been explored and implemented;depending on the"three bases"and"ten measures",the sustained,proportional and speedy TBM construction under the suitable geological conditions can be realized;and under the bad geological conditions,the function and performance of the equipment and the construction technology should be improved,so as to improve the engineering adaptability of TBM,and promote the scientific development and sustainable development of TBM construction technology.
