贵州山区公路建设中，高填方路堤居多，盖板涵是公路工程中涵洞的常见类型，

Highway construction in Guizhou mountainous area, mostly high embankment, culvert culverts in highway engineering common type, high fill culvert culvert such cracking is the largest type of disease. High fill culvert failure in security, the economy will have serious consequences and great losses. How to prevent cracking in high fill culvert is a critical issue. Therefore, this paper Guizhou Province "S304 Xinmin to Indian River county highway expansion project", specific examples of K48 + 800 high fill (fill 27 meters) cracking culvert project, combining literature, etc., to fill high Causes square culvert crack analysis of the disposal measures after cracking were studied.

In the construction of guizhou mountain road, the high-filled embankment is the most common type of culvert in highway engineering, and the high-filled cover plate culvert is the most disease type of such culvert. High-fillculum culvert cracking will have serious consequences and great losses in terms of safety and economy. How to prevent the cracking of the culvert of the high-fill cover cover is a very important problem. Therefore, in this paper, in view of the "S304 Xinmin to Injiang County Road Reform and Expansion Project" project in Guizhou Province, K48-800 high-filling (filling 27 meters) cracking cover culvert project specific examples, combined with literature, etc., to the high-fill edging cover culvert cracking cause analysis, after the cracking measures were studied.

In the highway construction in Guizhou mountainous area, the high fill embankment is the most common type of culvert, and the cracking of high fill slab culvert is the most common type of disease. The cracking of high fill culvert will cause serious consequences and great losses in safety and economy. How to prevent the cracking of high fill slab culvert is a crucial problem. Therefore, this paper analyzes the causes of cracking of K48 + 800 high fill (27 meters) slab culvert in the "S304 Xinmin Yinjiang County Highway Reconstruction and expansion project" in Guizhou Province, and studies the treatment measures after cracking based on the literature.<br>
