Abstract：This paper expounds the formation mechanism of the slide and settlement and the principle of the renovation in karst zone. Combined with the Meihua Mountain-Zhaotong section of Nei-Kun railway, the construction technology and the quality control process of grouting and renovation for railway subgrade in karst zone are given, emphasized the practicability in actual operation. It provides the reference basis for the analogous engineering in the future.
