摘　　要：在公路改建工程中,由于道路等级的提高,平、纵曲线指标要求及荷载等级也相应提高等,经常遇到旧桥加固、桥面抬高问题,其中又以中小跨简支体系结构居多。本文根据六叶公路改建工程实践,对简支体系桥面抬高的方式进行了分析,并提供设计计算算例供参考。As to raise road classification in highway re -building construction,index of level&longitudinal curve and load grade are all raised.In re-building,we often meet the problems of reinforce the bridge or raise the bridge surface which there are most in construction system of small and medium simple supporting.According to liu-ye highway engineering construction,we analysis the ways of raising surface of bridge in system of simple supporting,now we provide our engineering counting for reference.
