确定路基振动碾压次数的新方法

A New Method on Compactor Pass by Vibrating Rolling of Roadbed

以能量原理为基础 ,根据欲使现场土体达到规定的压实度 ,现场土体吸收的压路机的振动压实能与室内标准击实试验的击实功相等的事实 ,建立振动压路机～土体系统动力学模型 ,解出动力学方程 ,运用数学方法求出振动压路机的碾压次数。

On the basis of energy principle, the energy which site soil has absorbed from vibrating roller should be equal to the compaction effort that has been given to samples in standard compaction test indoors, according to the specified compactness that site soil should attain to . The dynamics model of vibrating roller-soil system is established, then, the dynamics equations are solved and compactor pass of vibrating roller is obtained by mathematics method.
