| 摘 要： | 地埋管道上实测的土压力并不是按现行计算方法假定形状分布的，其分布形式与管土的相对刚度及施工埋设方式密切相关。为此，依据现场实测和模型试验得到的地埋管道受力特征，在平面应变条件下，采用建立的管-土相互作用分析Vlazov模型来模拟管-土之间的相互作用，考虑管道不同的埋设条件、管周的不同充填介质及管-土相互作用引起的土压力状态等情况，建立了地埋管与土相互作用平面问题的传递矩阵分析法。并设计了可视化计算机软件，实现了计算手段的创新。运用此软件对现场埋管工程作了分析计算，并与实测结果进行比较，验证了所建立的计算方法的正确性。

| Abstract: | Soil stress measured on buried pipe is not distributed with the figure assumed by present calculation method. Its figure has close relation with relative stiffness between pipe and soil as well as construction method. Therefore, on the basis of stress characters obtained by field measurement and model test, under condition of plain strain, through simulating interaction between pipe and soil with Vlazov Model for interaction analysis, the new method with regard to different buried conditions, different fill-in material around pipe and soil stress status caused by interaction between pipe and soil, etc. is established. A visual computer software is designed on the new method; and calculating buried pipe tool innovation is realized. By using the software, the buried pipe in Shanghai was analyzed and the validity of the method was proved by compared with site measured result. |
