摘要
为合理分析重载交通下干线公路高韧化加铺结构力学性能,依托实体工程,采用路面力学计算程序,对2种高韧化加铺结构进行力学性能分析.结果表明,路面组合对结构受力具有重要影响,对拉压应变转换点位置影响不大,除路表弯沉外,路面高韧化加铺结构其他受力指标均优于普通半刚性结构,且旧路模量对高韧化加铺结构受力影响大于常规半刚性基层结构.
Abstract
In order to reasonable analyze the mechanical performance of high toughness overlay struc-tures on trunk highways under heavy traffic,relying on the entity engineering and using the pavement mechanics calculation program,the mechanical properties of two types of high toughness overlay structures were analyzed.The results show that the pavement combination has important influence on the structure,and has little effect on the position of the transition point between tensile and compres-sive strains.In addition to the deflection of the road surface,the other stress indicators of the high toughness overlay structure on the road surface are better than those of the ordinary semi-rigid struc-ture,and the influence of the old road modulus on the stress of the high toughness overlay structure is greater than that of the conventional semi-rigid base structure.
