击实试验结果准确与否直接影响到试验结果的准确性与工程质量.通过开展泥质板岩改良土的大量室内试验,将石灰、水泥按不同比例与不同含水率的泥质板岩拌和均匀,在不同击实条件下进行击实试验,确定了最大干密度和最佳含水率;并基于此研究了不同击实标准、不同外掺剂及掺灰量、水泥加水拌和延迟制样时间对击实试验结果中最大干密度和最佳含水率的影响.试验结果可为客运专线的设计与施工提供一定参考.
The accuracy of the compaction test results directly affects the accuracy of the test results and the quality of the project.Through carrying out a large number of laboratory tests on the clay-sodified soil, lime and cement are mixed with the clay-bearing slate with different water contents in different proportions , Compaction test was carried out under different compaction conditions to determine the maximum dry density and the optimum moisture content; and based on this, different compaction standards, different external admixtures and the amount of doped gray cement and water mixing delayed the sample preparation time Compaction test results of the maximum dry density and the best moisture content of the test results for passenger dedicated line design and construction provide some reference.
