| 摘 要： | 老路改造工程往往受限于道路现状条件,设计指标不能完全满足相应的道路设计规范要求,若强而为之则大大增加了工程改造成本,因此老路改造中的一些设计指标宜依据老路运行的实际需求,因地制宜,在满足需求且保证运行安全的基础上可适当调整某些设计指标的取值,达到改造工程的双赢。该文以成都市人民南路为列,依据道路的实际现状,对老路改造中的设计车速、车道宽度、通行净空等关键性指标的取值进行探讨。

| Abstract: | The reconstruction engineering of the old roads is limited by the present conditions of the roads sometimes.The design indexes can not fully satisfy the relative requirements of the road design criterion,and will greatly increase the engineering reconstruction cost if forced to do that.Therefore,some values of the technical indexes in the reconstruction of old road can be properly adjusted according to the actual operation demand of the old road by adjusting measures to local conditions and on the basis of ... |
