摘　　要：桥梁引道的沉降主要由地基沉降、填土路基沉降及路面结构层沉降三部分构造,根据分布状况可分为纵向和横向差异沉降。EPS轻质填料具有密度小、耐久性强、稳定性好的特点,适用于填筑桥梁引道路堤。实体工程中采用密度约20kg/m3的EPS块体材料填筑路基,能够有效提高路基稳定性和减小差异沉降。The settlement of bridge approach mainly include foundation settlement, filling foundation settlement and settlement of Pavement structure layer. According to the distribution status, it can be divided into longitudinal and transverse differential settlement. EPS light fill material is with features like small density, strong durability and good stability, being suitable for filling the bridge approach embankment. In the substantial project, EPS block material with a density of about 20kg/m3 is adopted for subgrade filling, so as to improve the subgrade stability and reduce differential settlement effectively.
