Abstract

The capacity expansion project of Yahu landfill site in Pingshan New District of Shenzhen City is based on the old landfill site. It will inevitably cause the inhomogeneity of landfill foundation settlement because of the different new landfill height and the complicated geological conditions, and then cause bending deformation of the permeate discharge guide tube. In this article, the method of layer-wise summation is firstly used to calculate the settlement of pipeline foundation. On the basis of the above settlement calculation, the model of multi-braced steel frame is established to analysis the maximum axial tensile stress and bending degree of pipe by displacement method. The research has a good reference value for judging the safe state of the pipeline under uneven settlement of foundation.
