摘要
喷混凝土是地下洞室开挖支护最基本的方式。传统的干喷工艺存在粉尘大、回弹高、混凝土质量不稳定等缺陷。根据湿喷钢纤维混凝土在拉西瓦水电站地下洞室中的应用情况,介绍了湿喷技术在支护工程中的优越性。
The steel fabric shotcrete is the most common manner in the excavation support of the underground cavern. There exist defects in respect of big dust, high rebound, and unstable concrete quality etc. in the traditional dry shotcrete. It intro duces the advantage of wet shotcrete technique in tbe underground supporting works.
