摘　　要：针对特厚冲积层钻井壁的施工条件和性能要求,提出了钻井井壁高强高性能混凝土的配制原则和配制途径,在大量试验的基础上选择了原材料,进行了C60-C70钻井井壁高强高性能混凝土的配制试验,得到了优化配合比,并成功地应用于工程中。Aiming at construction condition and performance requirement of drilling shaft lining in special deep alluvium, the preparation principle and preparation approach of high strength and high performance concrete of drilling shaft lining are brought forward. On the base of a great deal test, the raw and processed materials are chose and preparation tests of C60-C70 high strength and high performance concrete of drilling shaft lining are done. The optimizing mixing ratios are gained and have been successfully applied in engineering practice.
