立交匝道线形设计的探讨

Linear Design of Interchange Ramp

在进行匝道的平纵横设计时,除灵活掌握技术指标外,还应最大限度地优化线形,使得其与主线能顺适连接,保证行车的安全性和舒适性。结合工程实践,提出在进行立交匝道的平纵横设计时应注意的一些细节,可供同行参考。

In the plane, longitudinal and transverse alignment design of ramp, besides technical indexes should be mastered freely, the line shape should be optimized furthest in order to connect the main line smoothly, therefore the security and amenity can be ensured. Combining with the engineering practice, some details about the ramp＇s linear design which should be paid attention to are proposed. They can be consulted by peers.
