摘　　要：双护盾TBM在公路项目中应用较少,由于雅家埂隧道特殊的环境条件,首先对该项目应用TBM可行性进行分析;其次通过搜集到的类似项目资料,分析贯通平导+施工斜井+通风斜井方案和平导采用TBM+主洞爆破法方案在工期、造价上的优劣,同时对两种方案进行施工组织设计。研究结果表明,雅家埂隧道平导采用TBM+主洞爆破方案可以大幅度缩短工期,增加的投资额在可控范围内。The double-shield TBM has less application in the highway project.Due to the special environmental conditions around the Yajiageng tunnel,the application feasibility of TBM in the project is analyzed first.Then,by using the data collected from similar projects,the advantages and disadvantages in terms of duration and cost of two construction schemes are analyzed,one is pilot+inclined construction shaft+ventilation shaft,and the another is pilot using TBM and main tunnel by using drilling and blasting method.Meanwhile,preparation of construction organization of the two schemes is provided.The analysis results show that the scheme that pilot by using TBM and main tunnel by using drilling and blasting method can significantly reduce construction duration in Yajiageng tunnel,while the increased investment lies within the controllable range.
