地基土承受超载作用时就会产生沉降，在土体沉降作用下埋置于其中的管道，管壁就会产生变形甚至破裂。为分析地面超载对临近地下管线的影响，基于温克勒（Winkler）弹性地基短梁理论，应用Boussinesq解，考虑地面超载引起下卧层的沉降及地基土体的侧向移动对管道的影响，建立地面超载对埋地管道影响的分析计算模型，并采用有限差分法进行求解；通过算例分析了超载大小、位置，管道刚度、埋深、管径以及土体性质对埋地管道位移的影响；结果表明：超载大小、管道的刚度、埋深、管径对地下管道位移的影响较大，而当地基基床系数和超载离管道的距离增大到一定值时，地面超载对其影响将减弱。因此，需要考虑邻近超载对管道的影响，合理制定埋地管道的保护措施。

Ground would settle while ground is subjected to surcharge loads. The deformation or break would happen in the walls of the pipelines in the ground due to the settlement. This paper focuses on the effects of ground surcharge on adjacent buried pipelines. A calculation model is established with the theory of Winkler elastic foundation short beam and Boussinesq basic formulas, taking into account the impact of subsoil deformation induced by ground surcharge on pipelines. The solution is derived with the finite difference method. Consequently, cases are performed under various loads, location of the load, geologic condition, pipeline depth, diameter and stiffness of pipeline as well as property of soil. Results show that: after increasing to a certain threshold, the pipeline diameter and the coefficients of foundation bed would have a relatively small impact on the pipeline maximum displacement. However, the buried pipeline deforms significantly as the burial depth decreases. As expected, the maximum displacement of pipeline decreases while the pipe stiffness increases and the location of ground surcharge loads pose large effect on buried pipelines. So it is necessary to consider the surcharge loads and make a reasonable protective measure for buried pipelines.
