摘    要:玛柯河为南水北调西线一期工程规划引水河流,亚尔堂坝址段岩层以三叠系板岩为主,属于易软化较软岩。根据工程设计的总体要求,对坝址段岩体蓄水后的膨胀性做出预测,研究项目主要包括板岩的抗压强度、矿物成分、吸水率、膨胀率和膨胀压力等,并对影响膨胀指标间的因素做总结分析,根据软岩膨胀分级标准判断试验板岩属于非膨胀性岩石。

关 键 词:板岩  矿物成分  吸水率  膨胀指标  分级  南水北调西线工程

Abstract:The Make River is planned to be the water delivery river of phase-I works of West Route Project of South-to-North Water Diversion.The strata at Ya'ertang dam-site is mainly the triassic slate,which belongs to relatively soft rock and is easy to be softened.On the basis of general requirement of engineering design,we forecast the expansion condition of rock mass at the dam site after impoundment.The researches including the compressive strength,mineral composition,water absorption,swelling ratio and expansiv...
Keywords:slate  mineral composition  water absorption  swelling index  classification  West Route Project of South-to-North Water Diversion
