摘要
我国高速公路路网不断扩大,但桥梁台背沉降问题一直困扰着参建单位,因高速公路台背沉降带来的安全事故也屡见不鲜,该问题已经严重制约了我国高速公路的健康发展。论文根据成都市三绕蒲都高速公路建设的实际施工资料,利用新材料新技术对桥梁台背沉降问题展开研究,对气泡混合轻质土材料在高速公路上如何更好地应用起到了借鉴意义。
China’s expressway network is expanding.However,the subsidence problem of bridge abutment has been troubling the construction units all over the country,and the safe accidents brought by the subsidence of expressway abutment are also common,which has seriously restricted the healthy development of China’s expressway.Based on the actual construction data of Pu Du expressway in Chengdu Sanrao,this paper makes a construction study on the settlement of the back of abutment by using new materials and new technologies,which provides a reference for the better application of bubble mixture lightweight soil materials on the expressway.
