Application of Pressure Grouting in Teatment for Karst Subgrade

Abstract:

The treatment of karst foundation is one of the common problems in the highway construction. Combined with the grouting construction of kast subgrade for the highway of Changde-Zhangjiajie, this paper introduced the construction technique and interrelated construction parameter of the pressure grouting, and provided some corresponding treatment methods for special problems in construction. It provided the reference basis for the analogous engineering in the future.

Key words:karst; grouting; the highway of Changde-Zhangjiajie; subgrade
