Research on the Development and Application of Prefabricated Steel Shed Tunnels on Mountainous Highways
In order to effectively improve the geological disaster prevention technology for high-altitude collapse on mountainous roads,a research method of 1∶1 prototype testing and numerical simulation testing is adopted to study the design concept,construction methods,and impact dynamic response of the proposed new generation of prefabricated steel shed tunnel equipment.The results show that the construction speed of prefabricated steel shed tunnels is fast,the installation risk is low,and the protection level can reach 2 000 kJ.The research results have been successfully applied in the S467 line disaster prevention and control project,and have significant engineering application significance for large-scale promotion.
