本文介绍了自制的几种路面力学参数的量测仪具和路面试槽静动载实验装置及其测试技术。进行了单园和双园承载板及汽车双轮胎的静载和慢速动载下的路面应力应变的实验工作,并与弹性层状体系理论精确解和有限元法电子计算机计算结果作了对比分析,探讨了有关土基应力和路面应变随荷载和路面结构参数变化的基本规律,为制订我国柔性路面设计新规范提供科学依据。
This paper introduces several self-made measuring instruments of pavement mechanical parameters and static and dynamic test device of road surface test tank and its testing technology. The experimental work of pavement stress-strain under static load and slow dynamic load of single-park and double-park load-bearing plates and double-car tires was carried out and compared with the theoretical exact solution of the elastic layered system and the calculation results of the computer by finite element method Analysis and discussion on the basic law of stress and pavement strain with the load and pavement structure parameters changes, to provide a scientific basis for the formulation of new norms of flexible pavement design in China.
