【摘要】 采用等参数四边形实体单元模似地基板板块及地基，古德曼等参数节理单元模似板间连接状态和断板断缝工作状态，分析了断裂弹性地基板上加铺层的应力随板间连接程度、板和地基连接状况、筑板材料的弹性模量、加铺层厚度和地基局部软化等因素的变化规律．更多还原

【Abstract】 In dealing with the mechanics character of theoverlay on cracked plates on elastic foundation,isoparametric solid finite elements have been used to simulate the plates and overlay,Goodman interface element to simulate interfaces between plate and overlay,plates and foundation,also to simulate the cracks in plate.According to this,the stress in overlay with variety conditions have been presented in this paper.更多还原
