Soft Soil Foundation

Highway is an important channel to connect regional economic development, and is an indispensable part of modern transportation system. In view of the extensive nature of highway cover space and the existence of diversified construction environment, climate and geological influence in highway construction, soft soil foundation is one of the more typical geological forms. With wide distribution in our country, seen as a big difficulty, highway construction technology and directly affect the quality of highway construction, cost, if not properly handled, will cause the soft soil foundation highway engineering structure is not stable, prone to accidents in use. In this paper, we study the treatment of soft soil foundation in highway construction, and put forward some reasonable Suggestions.

Geological Conditions

Since the 21st century, the national economy of China has tended to fast develop, and the people's material life has been greatly improved. As the investment of the state in social infrastructure continues to increase, the domestic infrastructure construction has been in a rapid development, and especially the road and bridge construction projects have largely accelerated the development of the transportation and also the growth of the national economy in China. In the meantime, the geological conditions encountered in highway engineering are more and more complicated, so the requirement on the construction technology is continuously higher and higher, and finally certain difficulties are caused to the construction. In this paper, the construction technology of the graded granular cushion at the bottom of the subgrade in highway engineering is studied and discussed specifically.
