Advanced Support Technologies in Roadway

Abstract

In the continuous development and application of underground spaces (such as roads, tunnels and underground caverns), safe and efficient support technology is an important means to maintain the stability and integrity of roadways. Advanced support technology in- cludes the development of support materials with superior performance, the improvement and innovation of existing support theory, and the development of mechanical equipment with comprehensive functions. For example, the mechanical strength of shotcrete can be en-hanced by adding fibers [1,2], improving work efficiency and reducing safety risks through intelligent mechanical equipment [3,4], analyzing the movement characteristics of materials and the control of pipe jam during long distance pumping [5,6], and studying the support structure under complex geological conditions such as high in situ stress [7,8]. Therefore, with the improvement of occupational health requirements and complex and changeable geological conditions, the application of advanced support technology is particularly im- portant for underground work. Exchange and discussion of advanced tunnel support technology is conducive to the safe and efficient development of underground spaces.
