摘要
为检测评价路基压实效果,提出了一种新型塑性应变增量法。利用土层厚度实时检测装置测量新填土层的实时压缩沉降和应变。由压缩产生的塑性应变随碾压遍数递减,以当次碾压较上一次碾压的应变增量作为压实效果的评价参量。现场试验结果表明:利用塑性应变增量法采集数据快捷稳定可靠。该方法可用于评价路基压实效果。
A new plastic strain increment method is put forward to detect and evaluate the compaction effect of roadbed.The real-time compression settlement and strain of the newly filled soil layer are measured by using a real-time detection device for soil layer thickness.The plastic strain generated by compression decreases with the number of rolling compaction,and the strain increment of the current rolling compaction compared to the previous rolling compaction is used as the evaluation parameter for the compaction effect.The on-site test results show that:using the plastic strain increment method to collect data is fast,stable,and reliable.This method can be used to evaluate the compaction effect of roadbed.
