国家“十四五”规划纲要明确指出:要求平衡好各种交通运输方式的规模、结构、功能、布局和建设时序等,力求提高整体效率、避免资源浪费。普通水泥混凝土路面有不可重复利用以及开放通车时间较长的缺点,造成了工程资源的浪费,导致了效率的降低。而装配式水泥混凝土路面具有建设周期短、可重复利用等优点,是一种既经济又高效的路面结构形式,因此对装配式水泥路面的研究具有重要的理论与实际意义。本文全面梳理国内外装配式水泥混凝土路面的研究现状,以水泥路面设计规范作为设计依据,采用有限元方法及数值模拟软件ABAQUS,模拟得到不同外界条件下装配式水泥路面板块的力学响应规律,从而对板块结构形式进行设计、优化与验证,最终确定两种性能较优的板块结构供实际工程参考。主要研究内容如下:（1）系统总结国内外装配式水泥路面板块结构的研究进展,基于水泥路面设计理论确定了装配式水泥路面的结构模型,并通过调研水泥路面材料常用设计参数,建立了装配式水泥路面结构有限元模型,以研究装配式水泥路面板块的尺寸、接缝与空心三种结构形式。（2）整体设计装配式水泥路面板块的三种结构形式,利用有限元方法模拟标准轴载作用于不同位置的工况,计算分析单一力学响应指标对应的最不利荷位,得到各项指标随板块结构形式变化的规律,并确定装配式水泥路面板块结构尺寸为4×3×0.28m,接缝采用传力杆或圆形企口缝形式,板块空心截面形式为圆形。（3）详细设计传力杆、圆形企口两种接缝形式与圆形空心形式的局部尺寸,利用正交试验方法分析局部尺寸因素改变对各力学响应指标的影响,并运用熵权-TOPSIS法对多指标综合考虑得到了各局部尺寸的最优值,最终确定装配式水泥路面板块的全部结构形式。（4）结合理论分析方法建立温度荷载、动荷载与二者共同作用的路面结构模型,在不同外界条件作用下,分析所设计路面板块的力学响应变化规律,并验证了板块结构在最不利条件作用下满足极限断裂要求。
