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.
Abstract
The foundation of the spillway gates in Xinji Hydropower Station in Hanjiang River is disturbed due to the ar-tificial accumulated sand-gravel.Based on the conventional survey methods and the comprehensive application of the la-boratory 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 en-gineering 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.
