铁路隧道可溶岩与非可溶岩接触带施工技术研究

Study on the Construction Technology of the Contact Zone between Soluble and Non Soluble Rock in Railway Tunnel

在铁路隧道施工中,可溶岩与非可溶岩接触带施工风险极高,若麻痹大意,在施工过程及后期运营期间会存在较大的不良安全隐患,且会影响铁路隧道使用寿命。因此,在施工过程中制定科学、合理、有效、经济的接触带施工方案是该段落施工及后期运营极为重要的关键因素。针对接触带地质发育状况,进行动态设计,确保科学、合理、有效、经济的通过该段落。本文根据可溶岩与非可溶岩接触带发育状况,阐述了此类接触带的具体处理方法,对类似接触带的设计与施工积累了一定的技术经验。

In the construction of railway tunnel,the construction risk of the contact zone between soluble rock and non soluble rock is very high.If treated carelessly,there will be great adverse safety hazards in the construction process and later operation period,and it will affect the service life of railway tunnel.Therefore,formulating a scientific,reasonable,effective,and economical contact zone construction plan during the construction process is a key factor for the construction and later operation of this section.According to the geological development of the contact zone,the dynamic design is carried out to ensure the scientific,reasonable,effective and economic passage of this section.According to the development of the contact zone between soluble rock and non soluble rock,this paper expounds the specific treatment methods of this kind of contact zone,and accumulates some technical experience for the design and construction of similar contact zone.
