摘要
本文根据温度场研究结果,视碾压水泥混凝土(RCC)与沥青混凝土(AC)为各向同性热线弹性材料,土基和基层为各向同性线弹性材料,层间为连续接触,用三维等参元法计算RCC+AC路面结构翘曲温度应力,按Bradbury法进行整理,形成了计算RCC+AC复合式路面结构温度应力的实用方法。
n this paper, the thermal stresses of RCC and asphalt concrete composite pavement structure are analyzed using the temperature field results where RCC and AC are supposed to be thermal elastic materials, while subgrade soil and base course materials to be elastic materials. Three dimensional isoparametric finite element method was used to carry out the analysis with the assumption of full friction between each two layers. The analysis results are concluded with the Bradbury method so that a simple and rational thermal stress analysis method of the composite pavement has been developed.
