“六五”国家科技攻关项目“深厚覆盖层建坝研究”,经两年半联合攻关,共取得57项科技成果,使深厚覆盖层从勘探、取样、工程特性、建坝试验研究、理论计算和施工等方面都有一个飞跃。这将对加快水电建设的前期工作,缩短建设周期,降低工程造价等均具有重要意义。 本文综述了深厚覆盖层金刚石钻进与取样技术研究;SM植物胶的研制;GST—30型高压大三轴及平面应变试验机的研制;铜街子工程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方法研究和防渗墙墙体材料固化灰浆研究等主要成果。
During the “Sixth Five-Year Plan” project of “National Research Project on Deep Overburden,” 57 scientific and technological achievements have been made through joint research over the past two and a half years. The deep overburden has been developed from exploration, sampling, engineering characteristics, experimental study on dam construction, theoretical calculation And construction, etc. have a leap. This will be of great significance to accelerating the preparatory work for hydropower construction, shortening the construction period and lowering the construction cost. In this paper, the research on deep overburden diamond drilling and sampling technology; the development of SM gum; the development of GST-30 high pressure large triaxial and plane strain testing machine; the centrifugal model test of the left deep-seated rockfill dam of Tongjiezi project ; Research on comprehensive test technology of deep overburden and research on solidified mortar for anti-seepage wall material.
