摘要
根据土石坝坝体填筑质量传统检测技术存在的弱点,应用瞬态瑞利波检测技术对土石坝坝体填筑质量检测进行了研究与应用,给出了土石坝坝体各测点瑞利波频散曲线及反演分析结果,给出了土石坝坝体填筑材料瑞利波波速分布及填筑材料的密实性、均匀性,给出了土石坝坝体与坝基接触效果。将瞬态瑞利波检测结果与现场钻孔取样室内填筑材料干密度试验资料进行对比分析研究,建立了土石坝坝体填筑材料瑞利波波速与干密度的相关关系,为土石坝工程坝体填筑施工质量监控及全面评价提供了科学的依据。
According to the quality of earth-rock dam weaknesses of traditional inspection technology,Applying instantaneous Rayleigh wave inspection technology,research and application is conducted to inspection of dam body filling quality of earth-rock dam.The results of Rayleigh wave curve of frequency distribution and inversion analysis is given about all measuring point of earth-rock dam body.The Rayleigh wave velocity distribution and the density and uniformity of the filling material is given about earth-rock dam filling material.The effect of rock fill dam and foundation contacts is given.According to comparative analysis of the instantaneous Rayleigh wave inspection results and filling material dry density room experimental data at site of drilling and sampling,the correlation between dam body filling materials Rayleigh wave velocity and dry density of the earth-rock dam is established.The scientific basis is provide for quality control and comprehensive evaluation of the earth-rock dam body filling project.
