大堤防渗工程质量检测的几种试验方法

Some Testing Methods for Quality Inspection of Dyke Seepage Prevention Project

针对防渗工程质量检测与评价的复杂性,介绍了几种非常规方法在水库大堤防渗工程质量检测中的试验研究工作:①结合压水试验和注水试验2种方法的特点提出了钻孔压力注水试验;②应用面波和地质雷达等物探方法进行了一系列的无损检测试验。在大量试验基础上,改进了试验设备、完善了试验方法,并取得了可靠的成果,说明试验方法具有一定适用性。

In view of the complexity of quality inspection and evaluation for seepage prevention project, some un- conventional testing methods for the quality inspection of dyke seepage prevention project are introduced. The meth- od of borehole and pressure water-injection is proposed based on the characteristics of water pressure test and water injection test. In addition, non-destructive testing such as ground penetrating radar and surface wave methods are carried out. Through large amount of tests, the test equipment are improved and test methods are refined. Moreo- ver, reliable results are obtained which verified the applicability of these testing methods.
