| Abstract: | In this paper,taking karst subgrade in Liunan section of Hunan-Guangxi Railway capacity expansion engineering for example,the treatment program of karst subgrade is determined based on the degree of karst development.The grouting quality of karst subgrade is detected by water pressure(injection) test and comprehensive geophysical prospecting method.The result shows that the penetrability of the subgrade is decreased significantly and the wave velocity of the subgrade is increased obviously after grouting tr... |
