【摘要】 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.更多还原

【Abstract】 The accurate compaction test results directly decide the results of the test and the construction quality.This paper researches to the influence of maximum dry density and the optimum water content of the compaction test results,which take in different standards of compaction,different adjusting agent and weight of cement,mixing cement in delay time.The test results could provide reference of design and construction to the passenger express railway.更多还原
