摘 要: | 为解决解析方法不能直接计算U型槽结构变形的问题,利用FLAC3D软件对U型槽结构进行了数值分析,研究U型槽结构分析的新方法。总结了路堑U型槽结构在公路荷载下,地基反力、结构弯矩、结构变形的特点及规律,并与解析法分析结果进行了对比。对比结果显示,两种方法在边墙地基反力、结构弯矩方面分析结果较为接近,变化规律相同,底板地基反力分析结果差别较大。研究提出了数值分析方法的适用性。

Abstract: | In order to solve the problem that analytical method cant directly calculate the deformation of Ushape groove structure, this paper carried out numerical analysis on cutting U-shape groove with FLAC3D software to explore a new method for the analysis of such structure. In the paper, the characteristics and rules of both the ground reaction and the bending moment and deformation of the structure under highway load were summarized, and then compared with the results from the analytic method. The results show that for the ground reaction of side wall and the bending moment of structure, the results from the two methods are relatively close with the same change law; however, for the ground reaction of base plate, the results from the two methods have relatively large difference. In this study, the applicability of the numerical analysis was also proposed. |
