Abstract:
Submerged pipeline project may encounter anti 2uplift break and embankment settlement and deformation. How to de 2 termine the anti 2uplift buried depth and ultimate settlement in the design is a key problem to be solved to ensure project safety. In this paper, a cross2river submerged pipeline was taken as an example, an optimal algorithm based on finite element method was proposed to obtain a more practical and reasonable anti 2uplift buried depth in consideration of the overlying soil layer inten2 sity, flood passage and erosion, and earthquake load. In addition, ground loss was simulated based on the ultimate shrinkage of pipeline, and the vertical ultimate settlement and displacement were obtained eventually. The results can provide the basis for the project design and subsequent settlement monitoring.
