摘　　要：水泥混凝土路面在承受交通荷载和气候环境影响的情况下往往容易出现裂缝,断板等破坏现象。因此,深入分析水泥混凝土预制板的结构力学响应对于探讨合理的结构设计以及提升路面使用性能显得尤为重要。本研究以ABAQUS有限元软件为工具,建立了三维有限元模型,着重对预制水泥混凝土板在非移动荷载下的力学响应进行了详尽分析。首要目标在于确定模型的临界荷载情况,随后,基于此情况,深入探讨了静态荷载对路面结构各个参数的影响,从而在水泥混凝土预制板结构设计过程中,确立各个参数的合理范围。这些研究成果将为优化路面结构设计及提升使用性能提供有益的指导。Cement concrete pavement is often prone to cracking,slab breakage,and other destructive phenomena under the influence of traffic loads and climate environment.Therefore,in-depth analysis of the structural mechanical response of cement concrete precast panels is particularly important for exploring reasonable structural design and improving pavement performance.This study used ABAQUS finite element software as a tool to establish a 3Dfinite element model,focusing on a detailed analysis of the mechanical response of precast cement concrete slabs under non moving loads.The primary goal is to determine the critical load situation of the model.At present,based on this situation,the influence of static load on various parameters of the pavement structure was deeply explored,in order to establish a reasonable range of various parameters in the design process of cement concrete precast slab structures.These research results will provide useful guidance for optimizing pavement structure design and improving service performance.
