摘要

For the selection of superelevation rate on horizontal curve, the general method is based on a point-mass model, which regards vehicles operating on the curve as a point-mass and analyzes stress characteristics. However, vertical load and the lateral friction between tires and pavement vary dynamically. The difference affects driving safety for the choice of superelevation rate. This paper introduces safety margin to evaluate the rationality of superelevation rate and the difference between Design Specification for Highway Alignment JTJ 011-94 and JTG D20-2006 version. Recommended superelevation rate is calculated combined with engineering cases, to improve the rationality and safety of road superelevation rate selected by different designers.
