堤坝质量检测与分析方法研究

Study on Embankment Dam Quality Monitoring and Analysis Methods

结合温州地区水库大坝的特点,研究采用瑞利波法和探地雷达进行坝体的密实度检测,确定坝体内浸润线的位置。介绍了现场检测的基本原理和方法及所使用的仪器设备。测试分析表明,所测的三座土坝为均质土坝,工程质量较好,用探地雷达确定的浸润线位置与测压管实测结果相吻合。

In light of the characteristics of reservoir dam in Wenzhou, Rayleigh wave methods and GPR are used to detect the compact degree of the dam and to determine the position of saturation line. Principles and the methods of local monitoring as well as equipments used are introduced in the paper. The results of analysis show that three earth dams under test are uniform earth dams with sound quality, The position of saturation line determined by GPR complies with the result determined by the piezometric tube.
