为检测子级灰坝的碾压质量 ,运用一种轻便动力贯入仪对粉煤灰进行了一系列现场试验。通过这些试验 ,了解粉煤灰的岩土工程力学性质 ,尤其是其压实性质。同时 ,还做了一些静力触探试验及其它类型的动力触探试验。比较分析了这几种试验手段所获得的结果。根据粉煤灰坝的碾压要求 ,结合轻便动力贯入仪密实度检测判断 ,开展了一些碾压试验。结果表明 ,轻便动力贯入仪与其他测试方法有很好的对比性。 In order to test the roller compaction quality of the subgrade ash dam, a series of field tests on fly ash were carried out by using a portable power penetration meter. Through these experiments, understand the geotechnical properties of fly ash, especially its compaction properties. In the meantime, there are also some static penetration tests and other types of dynamic penetration tests. Comparative analysis of the results of these tests. According to the requirements of roller compaction of fly ash dam and light compaction penetration test, the roller compaction test was carried out. The results show that the portable power penetration instrument and other test methods are very good contrast.
