| 摘 要： | 避险车道是设置在连续长大下坡路段路侧并利用自身原理来消散失控货车能量,进而使失控货车安全停止的被动防护设施。分析了高速公路长大下坡路段避险车道的安全现状,提出了避险车道所存在的问题。并分析了不同结构设计参数对避险车道制动力的作用,提出了设计参数的最低使用要求。最后,依托仁赤高速公路上的避险车道,给出了优化设计和工程措施。

| Abstract: | Truck Escape Ramps are some passive protection facilities, which are set on roadside on continuous long and steep downgrade, using the inherent principles to dissipate energy of runaway truck. They can make the runaway truck keep safe. This article analyzes the security situation of the Truck Escape Ramps on long-steep downgrade of express, then presented the problems of TER. In addi- tion, this paper analyzes the braking capacity to which different structural design parameters can make contribution, and presented the minimum requirements of design parameters. Finally, Relying on the Ren-Chi expressway, presented the optimum design and engineering measures. |
