摘　　要：为了确定预制块道面板的结构参数,以苏-30飞机为荷载参数,利用ANSYS有限元分析软件对预制块道面版的尺寸、厚度、道面板的弹性模量、基层的厚度及回弹模量、结合程度和土基的回弹模量等因素进行了参数敏感性分析。结果表明:边长为0.5 m的预制道面板的受力状态最好;随着预制板厚度的增加,板底拉应力逐渐减小;预制板的弹性模量、基层和土基回弹模量以及结合程度对小尺寸版的影响较大,在实际工程应用中,预制道面板结构的设计参数还要参考具体情况进行调整。In order to study the structural parameters of precast concrete pavements （PCP）, the parameter sensitivity analysis was conducted by using ANSYS based on the load parameters of Su-30 aircraft.The analysis took into account the influence of following items. （i） the dimensions, thickness and elastic modulus of PCP. （ii） thickness and resilience modulus of the base layer. （iii） the coefficient of friction between the PCP and the base layer. （vi） resilience modulus of the soil base.The results indicated that the 0.5m-side-length panel performed well among the four types of panels;the bottom tensile stress decreased with the increase of the thickness of the PCP.The influences of elastic modulus of PCP, resilience modulus of the base layer and soil base and the degree of bonding between the panel and the base layer on small-sized panels are moderately obvious.In practical engineering applications,the design parameters of PCP are adjusted according to the actual situations.
