摘　　要：改革开放以来,我国的路轨交通得到了极快速的发展,尤其是这几年我国在隧道及地下工程领域已得到了很大的发展。随着像伶仃洋上的港珠澳大桥、深中通道等世纪工程拔地而起,至今已建成各类隧道超过7000座,隧道总长度超过4000km,隧道数量和总延长位居世界首位,并且目前仍以每年新建200-300km隧道的速度在增加。随着科技的进步,工艺功法的多样化,导致在项目前期施工策划阶段,对于隧道开挖的支护,选择那种施工工艺才能达到项目效益最大化,一直是个困扰的问题。鉴于此,本文将以实际工程为例,结合人工钻爆法与台车法两种工艺进行经济分析和探讨,以期为类似工程提供参考与借鉴。Since the reform and opening up,China's rail transportation has developed rapidly,especially in the fields of tunnels and underground engineering in recent years.With the construction of century old projects such as the Hong Kong Zhuhai Macao Bridge and the Shenzhen Zhongshan Expressway on Lingdingyang,more than 7000 tunnels of various types have been built,with a total length of over 4000km.The number and total extension of tunnels rank first in the world,and are still increasing at a rate of 200-300km of new tunnels built every year.With the advancement of technology and the diversification of construction techniques,it has always been a difficult problem to choose the construction technology that can maximize project benefits for tunnel excavation support in the early stage of project construction planning.In view of this,this article will take practical engineering as an example to conduct economic analysis and discussion by combining two processes:manual drilling and blasting method and trolley method,in order to provide reference and inspiration for similar projects.
