Abstract


In recent years, with the rapid development of the construction of the highway tunnel , the tunnel group the introduction of the concept of group and highway tunnels , tunnels linear elements defined in the analysis of a linear combination of the unreasonable , establish a reasonable way Tunnels linear , has become urgent need to address the issue. Qinling highway tunnel group relying on Western Han high speed in the papers , to analyze the linear combination of conditions , the impact of vehicular traffic behavior and traffic safety , and linear design of highway tunnel group improvement program , a highway tunnel security technology , operations management countermeasures the research provides a theoretical basis . Qinling highway tunnel group , the papers for the study , the Qinling highway tunnel group contains Suzaku tunnel Tunnel of Qinling One , Qinling Tunnel No. III Qinling Tunnel and its connection section , the first definition of the concept of a highway tunnel group of the tunnel the group of safety factors to do a simple analysis ; Qinling highway tunnel group Horizontal Alignment , vertical Alignment , cross-sectional linear and linear combination of horizontal and vertical analysis through research of the actual data , respectively . Secondly , combined with the research data , the uplink direction speed characteristics of the segment of Qinling highway tunnel group analysis; driver psychological changes characteristics under different line conditions and speed variation characteristics , relations through the fitting speed as well as the observation point position given the speed of change in the formula , to determine the impact of different linear conditions on speed model . Finally , the analysis of a different line of traffic safety , the binding characteristics of changes in the speed of different linear combinations of conditions to proposed tunnel group linear improvement program designed to improve the traffic safety of the tunnel group sections .
