湿磨细水泥-化学复合灌浆在三峡工程基础处理中的应用研究

Study on Fine Ground Cement and Chemical Compound Grouting for Foundation Treatment of TGP

针对三峡水利枢纽主体水工建筑物的基础处理工程,进行了全面、系统的灌浆新材料、新技术应用研究,特别是对类似于F215,F1096,F1050等断层破碎带作了专门加固处理现场试验研究。研究结果表明:采用高压湿磨细水泥-化学复合灌浆技术,大幅度提高了基础岩体的力学特性,使断层破碎带与软弱夹层形成连续的、完整的并较坚固的基础岩体。成功地解决了三峡工程岩体断层破碎带加固处理的难题。

The new grouting materials and technologies used for foundation treatment have been systemically studied from 1995 for TGP construction. Especially the special study of fault reinforcing treatment like f215, f1096 ,f1050 etc. has been made. By using fine ground cement and chemical compound grouting technologies, the mechanics characteristic of foundation rock has been improved in a great zone, so the fault zones and soft interlayers have been formed a consecutive, intact and hard rock body. It has successfully resolved the problem of fault reinforcing treatment in TGP.
