| 摘 要： | 采用三维有限元法对地基局部脱空条件下的CRCP进行荷载应力分析。分析中为考虑裂缝传递横向力的特性,提出位移边界一维搜索法。用编制的有限元程序对多种情况下CRCP内的混凝土、钢筋应力进行了计算,对路面的维护提出了建议,并讨论了CRCP应用于地基支承不良路段的可行性。

| Abstract: | Based on tridimensional finite element method,load stress of CRCP with weak support caused by local cavity is analyzed in this paper.In order to consider the characteristics of crack in transverse-force-transfer,the displacement-boundary-unidimensional-search method is presented.With the FEM program developed by the authors,calculation is performed about the stress of concrete and steel bar in CRCP with weak support.Some advice is given on CRCP's maintenance,and the practicability of constructing CRCP on those sections with weak subgrade is discussed. |
