摘要

借鉴复合材料力学的分析方法

对桥面板和桥面铺装层组合体系建立一种分层剪滞分析模型

研究了混凝土公路桥中组合体截面受负弯矩作用下铺装层的多重断裂问题

求出了普通混凝土和钢纤维增强混凝土铺装层的裂纹间距或裂纹密度

所得结果与某工程实例中普通混凝土桥面铺装层的破坏状况较吻合.计算结果表明

裂纹密度与远场施加荷载有关

施加荷载愈大

裂纹密度愈大

当施加荷载达到或超过某值时

铺装层会出现等间距的饱和裂纹群. 更多还原

Abstract

Using the analytical methods of composite mechanics for reference

a layering shear-lag model is established for the system composed of bridge deck ply and overlay.The multiple cracking problem of concrete bridge overlays for concrete highway bridges under minus moment is studied.Then the crack spacing or density of both conventional and steel fiber-reinforced concrete bridge overlays has been calculated.The results obtained are in a relatively good agreement with the failure situation for an eng...
