冲击碾压技术在辽宁滨海公路建设中的应用研究

在辽宁省滨海公路建设过程中,积极引进冲击碾压技术,以便提高土基承载能力、减少工后沉降量,增加路基稳定性.

Research on Application of Impact Rolling Tecchnique in Building of Liaoning Coastal Highway

In the course of Liaoning coastal highway building,the impact rolling techniques are actively imported in order to increase bearing capacty of soil matrix,reduce settlement affter construction and add stability of subgrade.By way of earlier phase's test,the paper systematically sums up compactive effects of impact rolling technology on the dumped rock sea filling subgrade,original soil foundation and sand-soil subgrade etc,determines the modulus of resilience,coefficient of deflection,settlement and lateral displacement of the subgrade under different impact-rolling work,and puts forward standards for control of impact-rolling in different filler and road conditions in responseto their trend of variation.
