【摘要】 在长隧洞的施工中,采用掘进机施工的工程越来越多,特别是国外掘进机的引进,加快了长隧洞工程的开发。而国产掘进机由于其性能和材质方面的原因,存在着一定的技术缺陷,通过国产SJ-45型掘进机在龙门滩工程的施工应用,分析和总结了SJ-45型掘进机的机械性能和存在的技术问题及处理结果,以利于国产掘进机的科研、生产和施工。更多还原

【Abstract】 During the construction of long tunnel, the more and more project have adopted TBM to carry out construction. Specially the introduction of overseas TBM speed up the development of long tunnel. But because of the performance and the production material, the TBM made in china exists some technical defects. Throughout the application of Type SJ-45 TBM in the construction of Longmentan Project, this paper analyzes and summarizes the machinery performance and existent technical problem. It is useful for the researching, production and construction of TBM made in china.更多还原
