在施工机械中动态检测土压实度的理论研究

Research on the Dynamic Inspection of Soil Compactibility in Construction Mechinery

常规的压实度检测试验要到压实过程完成之后才能进行。其主要缺点在于:(1)压实过程中不能测量和估价压实状态,无法对压实过程进行适应控制;(2)只能在施工后取少量的样本试验,所测数据带有局限性,可信度低;(3)试验消耗大量的时间,费用昂贵。如何使振动压路机发挥最大效能,即在压实过程中能实时显示路基的压实度值,促使压实过程动态检测的研究变得更为迫切。西德、日本等国在此领域走在前列。

The theoretical problem of dynamic inspection of soil compactibilit is analyzed by means of physical concept. practical inspection show that the theory is in agreement with the result measured by the designed soil compactness meter.
