随着经济发展,高速公路建设取得了突飞猛进的成绩,投入营运高等级公路越来越多,但从使用情况上看,出现了桥头跳车这个较为普遍的问题,尤其在一些软土地基地方更为严重,给高速行使中的车辆带来很多不适和安全隐患,同时,给养护部门带来了很大困难。本文通过分析产生桥头跳车的多种因素,指出常规处理措施的局限性,提出利用轻质材料填筑台背和提高台后地基承载能力来解决桥头跳车的施工措施,有效地避免桥头跳车病害产生,有效地改善行车条件,促进经济发展。
With economic development, highway construction has made rapid progress and more and more high-grade highways have been put into operation. However, from the point of view of usage, the more common problem of bridgehead jumping has emerged. In particular, in some soft foundation areas To serious, high-speed exercise in the vehicle brought a lot of discomfort and security risks, at the same time, to the conservation department has brought great difficulties. In this paper, by analyzing the various factors that lead to the vehicle jumping at the bridgehead, the paper points out the limitations of the conventional treatment measures and puts forward the construction measures to solve the bridgehead jumping by using the lightweight materials to fill the back and improve the bearing capacity of the foundation. Car disease, effectively improve driving conditions, promote economic development.
