公路隧道贯穿型溶洞跨越式桥梁施工技术探究

Research on Construction Technology of Highway Tunnel Penetrating Karst Cave Spanning Bridge

随着我国路网覆盖面积的不断扩大,一些公路工程在施工过程中受客观条件限制需要在贯穿型溶洞地区进行隧道施工,给隧道工程的建设带来了较大的难度。与传统的灌注技术相比,新型的跨越式桥梁技术不仅可有效减少资源的消耗,降低施工成本,而且其施工的质量效率也更高,因此在公路隧道的贯穿型溶洞施工中得到了越来越广泛的应用。施工单位应充分了解跨越式桥梁的各项施工技术要点,并结合工程的实际情况,提高技术应用的科学性和规范性,从而确保公路隧道工程的顺利实施。

With the continuous expansion of the coverage area of China’s road network,some highway projects are subject to objective conditions during the construction process,and tunnel construction is required in penetrating karst cave areas,which has brought greater difficulties to the construction of tunnel projects.Compared with the traditional pouring technology,the new type of spanning bridge technology can not only effectively reduce the consumption of resources and reduce the construction cost,but also the quality and efficiency of its construction is higher.Therefore,it has been used more and more widely in the construction of penetrating karst caves in highway tunnels.The construction unit should fully leap over the various construction technical points of the bridge and combine with the actual situation of the project to improve the scientificity and standardization of the technology application,so as to ensure the smooth implementation of the highway tunnel project.
