某试验路段冲击碾压技术与孔隙水压力监控

Impact-rolling Technology and Pore Water Pressure Monitoring of Certain Test Section

在公路路基施工碾压过程中,每轮冲碾的时间间隔是一个重要的施工参数。考虑到现场条件的不便,通过实测数据重点分析孔隙水压力和地下水位的时变规律,提出用反算现场频率来指导冲碾施工的方法,对同类工程施工具有一定的参考价值。

During the rolling process of highway subgrade construction,the interval of impact-rolling is a very important construction parameter.Considering the unfavorable field condition,pore water pressure and time-changing law of ground water level are selectively analyzed by measured data.The method that impact-rolling is directed by back calculate field frequency is proposed,which provides references for similar engineering construction.
