The deformation of culverts is influenced by various factors,among which construction tech-niques and construction sequence play key roles.To mitigate the deformation of small and medium-sized culverts and improve the quality and safety of the project,based on the fundamental data of a certain pumping station project,a three-dimensional numerical model was established to simulate two construction schemes:stepwise construction and simultaneous construction.The influence of the construction sequences on the deformation of buildings and foundations was analyzed.It was discovered in the research that when there is a relatively thick weak interlayer in the foundation soil layer,the simultaneous construction of the culvert and the adjacent buildings has a better control over the overall deformation of the foundation,and the resulting uneven settlement is smaller than that caused by the stepwise construction.
