摘要
黄登大桥左、右岸桥台由于受地质条件和拱座后台基础开挖影响,不适宜做重力式桥台,经过多方案比较后,选择加筋土桥台作为桥台型式。桥台型式选定以后,根据桥台的高度和长度对桥台进行布筋设计,然后根据布筋设计情况,对加筋土桥台进行设计荷载作用下的各种稳定性验算,验算结果表明,黄登大桥加筋土桥台的各种稳定性均满足规范要求。目前黄登大桥加筋土桥台已按设计要求施工完毕,并且安全运行3 a多没有出现任何问题,实践表明黄登大桥加筋土桥台的设计结果是满足规范要求并且满足工程需要的。
Both of the left bank abutment and the right bank abutment of the Huangdeng bridge are not fit to be de -signed to be of gravity type due to the geological conditions and excavation of the background foundation for the arch abutment .After comparison between a number of alternatives the reinforced concrete abutment was selected as the type of the bridge abutment .The bridge abutment reinforcement was designed according to the height and the length of the abutment on selection of the type of abutment .Then various stability calculations of the reinforced concrete a-butment were checked under the design load according to the design of reinforcement for the reinforced concrete bridge abutments .The calculation check indicates that the stability of the reinforced concrete abutments of Huang -deng bridge meets the requirements of the specifications .The construction of the reinforced concrete abutments of Huangdeng bridge were completed according to the design requirements , which have been under operation for more than 3 years without any problem .The practice shows that the design of the reinforced concrete abutments of Huangdeng bridge satisfies both the specifications and the need of the project .
