摘要
研究目的:通过对水泥改良土击实标准和方法的分析和研究,进一步了解延迟时间对水泥改良土工程特性的影响。研究结果:延迟时间对击实干密度及无侧限抗压强度有一定的影响,取延迟3~5 h的击实干密度进行现场质量控制能够保证无侧限抗压强度满足设计要求。
Research purposes:Impact from delaying on features of cement-modified soil can be concluded through analysing and making researching on cement-modified soil compaction method. Research results:Delaying impacts dry compaction density and unconfined compressive strength.Adopting dry compaction density with 3-5 hours delays for site quality control will ensure that unconfined compressive strength meets the design requirements.
