溶洞是石灰岩在水中长期溶蚀的结果,工程中溶洞大部分情况下可以考虑为一种不良地质。溶洞十分发育的地段线路要选择绕避,如没有选择绕避,则要根据实际情况对基础下的溶洞做相应处理,本文笔者结合实际的溶洞施工处理案例,对某溶洞的自密实混凝土回填技术措施进行了探讨,仅供参考。
Caverns are the result of long-term dissolution of limestone in water. In most cases, the cave in engineering can be considered as an unfavorable geology. If there is no choice to circumvent, the underground caverns should be dealt with according to the actual situation. In this paper, the author combined with the actual cases of cavern construction and treatment, the self-compacting concrete backfill technology of a cavern Measures were discussed for reference purposes only.
