Highway construction in Guizhou mountainous area mostly high embankment, culvert road engineering is a common type of culvert, 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 the project K48 + 800 high fill (fill 27 meters) cracking culvert works with literature data and so on, high fill cap Causes plate culvert crack analysis of the disposal measures after cracking were studied.

Guizhou mountain highway construction in the high-filled embankment, cover slab is a common type of culverts in highway engineering, high-filled cover slab culvert cracking is the most such culvert disease type. 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, this paper for Guizhou Province, "S304 Xinmin to Injiang County Road Reform and Expansion Project" project K48-800 high-filling (filling 27 meters) cracking cover culvert project concrete examples combined with literature, etc., the cause of the high-fill cover cover cul-al-severance analysis, the cracking after the treatment measures were studied.

In Guizhou mountainous highway construction, high fill embankment is the most common type, slab culvert is the common type of culvert in highway engineering, and 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 (27m) slab culvert project in the "S304 Xinmin Yinjiang County Highway Reconstruction and expansion project" in Guizhou Province, and studies the treatment measures after cracking.<br>
