偏载和低温条件下复合应力吸收夹层对应力强度因子的影响

Impact of Multiple Absorbing-Stress Interlayers under Slanting Loading and Low Temperature on Stress Intensity Gene

基于应力强度因子理论,针对偏载和低温2种不利情况,计算设与不设ISAC的水泥混凝土板上加铺沥青层修筑的CC-AC复合式路面结构最不利位置的应力强度因子。通过对比应力强度因子的大小,得出ISAC可以有效减小应力强度因子,说明ISAC有较好的防裂效果。

Based on the theory of stress intensity gene, aiming at the slanting loading and low temperature, calculating the stress intensity gene in the most unfavorable locations in CC-AC multiple road surface structure constructed with cement slabs of concrete with asphaltum with or without ISAC is done. By comparing the quantity of the stress intensity gene, a result was got that ISAC can effectively reduce the stress intensity gene, which shows that ISAC has good anti-splitting effect.
