Aiming at the actual engineering problem of influence of foundation pit excavation on underground pipelines nearby, basing on elastic foundation beam theory, the calculation method based on field test ground settlement curve of calculating the influence of foundation pit excavation on underground pipeline nearby is proposed. This method makes up the shortage of supposing the ground settlement curve above underground pipeline to be parabola, which makes the calculation result more accurate. Finally, the solution process of this method is illustrated through an engineering example. The vertical displacement equation of underground pipeline is obtained, and its value solution is solved with Matlab software, which is in good agreement with that of field test.
