摘要
半刚性基层裂缝的产生和发展很大原因是受到荷载作用,由交通荷载重复作用而造成的疲劳裂缝属于荷载型裂缝。文章结合广西路网工程建设实际状况,利用有限元计算模型分析半刚性基层受荷载作用开裂的情况,揭示基层荷载型裂缝对路面结构的影响。
The formation and development of semi-rigid base is mainly caused by the lateral load.The fatigue cracking that caused by the repeating work of traffic belongs to lateral load crack.Combined with the road networking construction condition of Guangxi,the article use limited ele-ment calculation model to analyze the cracking in semi-rigid based and reveals its influence on road structure.
