摘　　要：路桥过渡段路基沉降病害频发,易引发桥头跳车,导致行车不稳,造成交通事故。文章简要分析路桥过渡段路基沉降原因,结合工程情况,制定路基沉降填土方案,提出施工措施。结果表明,工程采取8%石灰土掺入填土,严格控制施工要点,能够提高抗压强度,减少压缩系数与最大干密度,满足工程要求。The frequent occurrence of roadbed settlement diseases in the transition section of roads and bridges can easily lead to vehicle jumping at the bridgehead,resulting in unstable driving and causing traffic accidents.The article briefly analyzes the causes of roadbed settlement in the transition section of roads and bridges,and based on the engineering situation,formulates a roadbed settlement filling plan and proposes construction measures.The results show that by adding 8%lime soil to fill soil and strictly controlling the construction points,the compressive strength can be improved,the compression coefficient and maximum dry density can be reduced,and the engineering requirements can be met.
