摘要:
为研究内蒙古西北地区三种土样的干压实特性，开展了室内击实试验和干压实下土样密度与击实功的对应关系分析．试验结果表明：三种土样均具备了干压实和湿压实双重特性；土样在一定范围内随着击实功的增大，密度也随之增大，提出了干压实下三种土样的最佳击实次数和对应的最大密度．基于室内干压实试验与现场施工机具的转换关系，提出了不同吨位下振动碾压机具的碾压控制指标．通过变换松铺厚度值，得出不同吨位下振动碾压机具的碾压遍数．
Abstract:
In order to identify the dry compaction characteristics of 3 types of soil samples in Northwest region of Inner Mongolia, the indoor compaction test and the corresponding relation between the density and compaction work in the case of dry compaction were analyzed. The results show that the 3 types of soil samples have dual characteristics of dry compaction and wet compaction. To some extent, the density increases with increasing compaction work, so the optimal number of compaction and corresponding maximum density for the 3 soil samples was proposed. Based on the study above, the conversion relationship were carried out based on indoor dry compaction test and the field construction machines in order to investigate the rolling control index of the vibratory roller with different tonnage. The rolling times of vibratory roller with different tonnage can be obtained through transforming slackly lay thickness.
