天然砾石土心墙防渗土料在水库工程中的应用研究

Application Research of Natural Gravelly Soil Core-wall Impervious Material in Reservoir Engineering

依托松林水库工程,通过设计前期、现场碾压试验以及心墙填筑后第三方检测、钻孔检测等试验成果,论证了天然砾石土作为心墙防渗土料的可行性。通过充分的前期试验研究,现场碾压试验论证并拟定合理的碾压参数后,可采用天然砾石土作为防渗土料。为缺乏粘土料源,或为尽量减小料场开采范围以降低地表扰动等类似中、小型水库工程提供了有力的实践依据。

Based on the Songlin Reservoir Project, the feasibility of using natural gravelly soil as core wall impervious material is demonstrated through the preliminary design, field rolling test, third-party detection and borehole detection after core wall filling. Natural gravelly soil can be used as impervious material after sufficient preliminary test, field rolling test and reasonable rolling parameters are determined. This paper provides a strong practical basis for similar small and medium-sized reservoir projects, such as the lack of clay material sources or the minimization of the mining scope of the material yard to reduce surface disturbance.
