完整极硬岩TBM施工辅助破岩方法研究现状及展望
Research status and prospect of assisting rock breaking methods for TBM tunnelling in extremely hard rocks
摘要
Abstract
In recent years,with the increase of the difficulty of TBM tunnel construction,the problems of low boring efficiency,fast wear of cutters,damage of TBM components,rockburst and other problems have occurred during the excavation of extremely hard rock tunnels,which have seriously reduced the safety and efficiency of TBM tunnel construction.This article provided statistics on the construction of extremly hard rock tunnels at home and abroad in recent decades and described and analyzed the problems encountered in the construction.The article introduced a series of assisted rock breaking methods,focusing on water jet,microwave,laser,plasma,and dry ice powder pneumatic rock breaking methods,and discussed the advantages and shortcomings of each method.At present,although there are several kinds of methods that have the prospects to assist the TBM breaking rock,there are still shortcomings with the TBM excavation,and further in-depth research is needed.关键词
