摘　　要：根据对现行有关涵洞病害的调查分析 ,并结合现场试验及相关资料 ,对高填土路基中涵洞土压力及其土体变形的影响因素和规律进行了分析研究 ,并在此基础上提出合理利用填土沉降差减小涵洞土压力的方法。According to the investigation on the distress of culverts, the in-situ test and its relevant data, this paper discusses factors influencing the earth pressure on the culverts in the embankment and the deformation of the soil body around culverts. Also, it put forwards to a method to reduce the earth pressure by the reasonable use of the difference of settlement of fill, on the basis of the above analysis.
