摘要
汉江新集水电站泄水闸地基部分因人工堆积砂砾石而扰动,为确定其工程特性,基于常规勘察手段并综合运用室内大型压缩试验、三轴剪切试验、渗透变形试验及原位大型抗剪强度试验,系统研究了人工堆积砂砾石层的物理、力学及渗透特性,取得了较为安全、可靠的岩土参数,为工程设计、施工提供了重要技术支撑,制定了较为经济、合理的处理措施。可供类似工程地质条件的勘测、设计与施工借鉴。
The foundation of the spillway gates in Xinji Hydropower Station in Hanjiang River is disturbed due to the artificial accumulated sand-gravel.Based on the conventional survey methods and the comprehensive application of the laboratory large-scale compression tests,tri-axial shear tests,seepage deformation tests and the in-situ large-scale shear strength tests,the physical,mechanical and seepage characteristics of the artificial accumulated sand-gravel layer are studied systematically.Reliable geotechnical parameters are obtained,which provide important technical support for engineering design and construction.Also,economical and reasonable treatment measures are proposed.The results can be useful reference for the survey,design and construction of projects with similar geological conditions.
