从淮河出山店水库的斑脱岩事件到葛洲坝工程泥化夹层恶化,黏土岩泥化预测研究
FROM THE BENTONITE INCIDENT AT THE CHUSHANDIAN RESERVOIR PROJECT TO PREDICTION RESEARCH OF CLAYSTONE MUDZATION AT THE GEZHOUBA PROJECT
-
摘要: 在1958年河南出山店水库建设中，因对坝基中斑脱岩在工程运营中工程性质的变化问题缺乏研究而被迫下马。10年后，在葛洲坝工程建设中又遇到了同类问题。多年的宏观微观研究结果表明，黏土岩（斑脱岩）泥化夹层的形成是层间剪切破坏的结果。因此，坝基中黏土岩不会产生泥化。Abstract: Reservoir project of the Chushandian was get downed in 1958a, Because of lacking research for problem on the properties change under engineering condition. After 10a, Gezhouba construction project also met with similar problem. Macro and micro reasearch results show the mudzation seam of claystone is caused by interbedding shear failure of rock structure. For this reason, the claystone in dam foundation is stable.
