摘要
通过大量的试验研究和工程类比,论证了糯扎渡水电站工程防渗土料采用掺砾料的必要性,并初步确定掺砾比例和土料压实标准;通过对试验成果的整理分析,提出了糯扎渡工程掺砾土料的工程特性参数;研究成果表明,采取一定的工程措施后,糯扎渡的所选土料场的土料可以满足坝高260m级心墙堆石坝防渗土料的要求。
A lot of experimental study and project analogy showed that it is necessary for the earth material as seepage control material to adopt the earth mixing gravel in the Nuozhadu project. Meanwhile, the proportion of gravel material and the degree of compaction for earth material have been preliminarily determined. Based on the analysis of test results, this paper puts forward the project parameters of earth mixing gravel for the Nuozhadu project. The research results showed that the earth material on the selected site when some engineering measures are taken can meet the requirement of the earth material for seepage control of the rockfill dam with core wall with the height of 260m.
