高速公路岩溶隧道施工安全

高速公路岩溶隧道施工安全高速公路岩溶隧道施工安全 摘要：随着我国道路交通安全设施的集中修建，在一些岩溶地质情况下修建高速公路的情况越来越多，在岩溶地质条件下修建隧道的长度也越来越长，为防止在施工过程中发生由于地质条件引起的渗漏、塌陷、滑坡等工程事故，在施工过程中，针对这一特别的地质，在充分评估的基础之上，对岩溶隧道进行相应的支护作业，保证施工过程的安全是一切工作的前提。文章就从分析高速公路施工过程中岩溶隧道的潜在风险入手，结合实际案例，重点讨论了岩溶隧道施工过程中的支护的要点，为整个施工过程中的安全提出了相对有效的方案。 关键词：高速公路；岩溶隧道；支护；施工安全 Abstract: along with the road traffic safety facilities built on, in some karst geological conditions of repair highways, more and more in the karst geological condition, the length of the tunnel construction is also more and more long, to prevent happens in construction process because of geological conditions caused by the leakage, subsidence, such as landslide engineering accident, in construction process, according to the special geology, in full on the basis of evaluation, karst tunnel for the corresponding supporting homework, ensure the safety of the construction process is all the work of the premise. This paper from the analysis of the highway construction process of the potential risk of karst tunnel, actual case, focus on the karst tunnel construction process of the supporting point for the whole construction process of the security puts forward relative effective solutions.
