In this paper, using the geological survey, site monitoring, checking and using the Midas theory stress analysis software modeling carried stress and deformation analysis and other measures, after cracking "K48 + 800 high fill culvert" engineering research, analyze its cracking Causes. According to the causes cracking, Treatment propose different solutions. For program from structure, cost, and other than the selected period, to determine the best solution. Reinforcement of the theoretical stress analysis and utilization of Midas checking software modeling carried out by the force and deformation analysis method of determining the final reinforcement measures, after the completion of the project, the strengthening effect of culverts dim survey to prove that the disposal measures feasibility.

本论文运用地勘、现场监测、理论受力分析验算和利用Midas软件建模进行受力及变形分析等措施，对开裂后“K48+800高填方盖板涵”工程进行研究，分析其开裂成因。根据开裂成因，提出不同的处治方案。从结构、造价、工期等方面进行方案比选，确定最佳方案。对该加固方案采用理论受力分析验算和利用Midas软件建模进行受力及变形分析的方法，确定最终的加固措施，在工程竣工后，对该涵洞的加固效果进行调勘，以证明处治措施的可行性。

In this paper, by means of geological exploration, field monitoring, theoretical stress analysis and checking calculation, and stress and deformation analysis by using Midas software modeling, the "K48 + 800 high fill slab culvert" project after cracking is studied, and the causes of cracking are analyzed. According to the causes of cracking, different treatment plans are put forward. From the aspects of structure, cost and construction period, the scheme comparison is carried out to determine the best scheme. The method of theoretical stress analysis and checking calculation and stress and deformation analysis by using Midas software modeling is adopted for the reinforcement scheme to determine the final reinforcement measures. After the completion of the project, the reinforcement effect of the culvert is surveyed to prove the feasibility of the treatment measures.
