摘　　要：针对超高设置的方式,全国各地采用方式存在不同的情况。从汽车行驶的受力及稳定行方面入手,分析了设置超高的原因,以及设置超高的时机。根据超高过渡段与缓和曲线的长度关系,以及平面设计采用的线形,结合527国道新昌大市聚至嵊州黄泽段工程超高设置方案,提出了三种超高设置方式,分别为当超高渐变段长度与缓和曲线长度接近,可全缓和段设置超高;当缓和曲线长度比超高渐变段长度长很多时,可在部分缓和段设置超高;当平面线形为S形时可采用公切点设零破的方式设置超高。There are different ways to set superelevation all over the country.The reasons for setting superelevation and the timing of setting superelevation are analyzed from the aspects of force and stability of vehicle driving.According to the length relationship between superelevation transition section and spiral curves,as well as the alignment used in plane design,and in combination with the superelevation setting scheme of Xinchang Dashiju to Shengzhou Huangze section of National Highway 527,three superelevation setting methods are proposed.namely,when the length of superelevation transition section is close to the length of spiral curve,superelevation can be set in the whole spiral curve section;When the length of spiral curve is much longer than the length of transition section of superelevation,superelevation can be set in some transition sections;When the plane alignment is S-shaped,the superelevation can be set by setting zero slope at the common tangent point.
