我院承担的国家“六五”重点科技攻关项目“大型水电站开发“中的子项“深厚覆盖层建坝研究”课题,在水电地质勘探基础处理公司、河海大学、四川简阳水电设备厂等单位协作配合下,自1983年6月起,经过两年半的努力,共取得57项成果,其中砂卵右覆盖层取样技术、SM植物胶的研制、GST-80型高压大三轴及平面应变试验机研制、铜街子左深槽堆石坝离心模型试验研究、深厚覆盖层综合测试技术研究、防渗墙固化灰浆材料的研究和应用等均属国内首创,填补了国内空白。深厚覆盖层防渗墙及堆石坝空间非线性弹塑性应力应变有限元计算和分析成果直接应用于铜街子工程中,填补了我国
The project of “Deep Overburden Building Research”, a subproject of “Sixth Five-Year Plan” key scientific and technological project “Development of Large-scale Hydropower Station” undertook by our college, is one of the most important projects in hydropower geological exploration basic processing company, Hohai University, Sichuan Jianyang Hydropower Equipment Factory In cooperation with the unit, since June 1983, after two and a half years of hard work, a total of 57 achievements were obtained. Among them, the sand and egg right overburden sampling technology, the development of SM plant gum, the GST-80 high pressure large triaxial and plane Development of strain testing machine, Centrifuge model test for Tongjiezi left deep-seamed rockfill dam, research on comprehensive test technology of deep overburden, research and application of anti-seepage wall solidified mortar material belong to the domestic initiative, filling the domestic blank. Non-linear elastic-plastic stress-strain finite element calculation and analysis results of deep overburden impervious walls and rockfill dam are applied directly to Tongjiezi project, which has filled our country
