In this paper, taking 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 causes cracking . The cracking in the proposed scheme different Treatment, in terms of structure for the program, cost, and other than the selected period, to determine the best solution. Reinforcement theory stress analysis using the checking and using the Midas software modeling carried out by the force and deformation analysis to determine the final reinforcement measures, tune survey of the culvert reinforcing effect after completion of the project to demonstrate the feasibility of the disposal measures .

本论文采取地勘、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以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, the measures of geological exploration, field monitoring, theoretical stress analysis and checking calculation, and stress and deformation analysis by using Midas software modeling are taken to study the "K48 + 800 high fill slab culvert" project after cracking and analyze the causes of cracking. According to the causes of cracking, different treatment schemes are put forward, and the best scheme is determined by comparing and selecting schemes from the aspects of structure, cost and construction period. In order to determine the final reinforcement measures, the theoretical stress analysis and checking calculation are adopted for the reinforcement scheme, and the stress and deformation analysis are carried out by using Midas software modeling. After the completion of the project, the reinforcement effect of the culvert is surveyed to prove the feasibility of the treatment measures.
