| Abstract: | Professional grouting teams are introduced and grouting technologies are optimized to improve the grouting efficiency and to guarantee the safe and rapid construction so as to pass through the karst sections of Xiangshan tunnel successfully. The original grouting plans, grouting technologies and grouting effect assessment standards are optimized and studied and grouting technologies for the karst sections of Xiangshan tunnel are proposed. In the end, the grouting effect is guaranteed and the construction progress is accelerated. The practice proves that the technologies optimized have significant economic and social benefits and are worth to be popularized in similar works. |
