In the vehicle-load stress analysis, the orthogonal anisotropic membrane model is established by treating the longitudinal bars as continuum, and three dimensional finite element analyses is carried out with the consideration transverse crack. 荷载应力分析中,将CRCP中纵向钢筋作连续化处理,建立了正交各向异性薄膜单元,对考虑裂缝条件下的CRCP荷载应力进行了三维有限元分析。
