摘　　要：砌块路面在城市人行道建设中使用广泛,但由于砌块路面厚度的确定受多种因素影响,而目前又尚无公认的设计理论和方法,现有规范推荐的等效厚度法和典型结构法也还不能很好地适用于不同情况,因此在城市人行道结构设计中不合理的情况时有发生。由此以400 mm×600 mm大型砖为例建立有限元模型进行分析,得到不同荷载、砂浆质量工况下人行道面砖计算厚度,再通过对有限元法和规范方法的试算结果进行对比,提出了不同情况下较为适宜的人行道路面结构设计方法,并认为该方法对受人行道结构设计问题困扰的同行有一定的借鉴意义。The block pavement is widely used in urban sidewalk.However,the determination of block pavement thickness is affected by many factors and there is no recognized design theory and method at present.The equivalent thickness method and the typical structure method recommended in the existing specifications are not well applied to different situations so that unreasonable structure design occurs from time to time in urban sidewalk structure design.The 400 mm×600 mm large brick is analyzed by finite element model and the calculated pavement brick thickness under different load and mortar mass conditions is obtained.Through the comparison of the test results between finite element method and standard method,the more suitable pavement structural design method under different conditions are proposed.The method is considered to have certain reference for sidewalk structure design.
