带斜井石质隧道施工方案

Construction scheme of stone tunnel with inclined shaft

通过对集双高速公路集安至通化段JTL03合同段五女峰隧道施工方案的研究,从总体施工流程、施工准备、洞口边仰坡及明洞开挖防护施工、仰拱混凝土施工、二次衬砌施工、斜井施工等方面,系统的论述了带斜井石质隧道新奥法原理钻爆施工的成功经验,为今后的带斜井石质隧道的施工提供必要的实践经验和理论知识。

Through the study on the construction scheme of Wunvfeng Tunnel in JTL03 contract section of Ji’an-Tonghua section of Jishuang expressway,from the overall construction process,construction preparation,excavation and protection construction of side slope,open tunnel,and inverted arch concrete construction,secondary lining construction and inclined shaft construction,systematically discussed the successful experience of drilling and blasting construction of rock tunnel with inclined shaft based on NATM principle,so as to provide some practical experience and theoretic knowledge for the construction of stone tunnel with inclined well.
