摘要
分析了配制高强混凝土的途径和影响井壁极限承载力的主要因素，提出了减薄井壁厚度的主要技术措施，研究了硅粉高强混凝土等的配比及特性。
In this paper, the ways for compounding high-strength concrete and main factors of holdingup the shaft-wall ultimate capacity are ana1ysed; the main technological measures of reducing shaft-wallthickeness are advanced; and the cornpounding ratios and characteristics of silicon powder high-strengthconcrete are studied.
