摘　　要：无砟轨道铁路附近新建建筑物容易引起既有铁路的变形,如何选择合理的地基处理措施、相对准确的变形分析方法等是必须思考的问题。通过对某工点的计算、地基处理措施的选择、观测数据的对比分析,提出了新建工程地基处理尽可能采用非取土桩、合理的施工顺序等几点建议。The new buildings built near ballastless track are likely to cause deformation of the existing railway. Therefore, how to choose a reasonable ground treatment measure and a relatively accurate deformation analysis method are the issues which must be carefully considered. This paper, based on a certain project site, illustrated how to calculate the project site, how to select the ground treatment measures, and how to comparatively analyze the observation data. This paper suggested that, the piles without earth digging should be employed as much as possible when doing ground treatment of the newly-built project, and should be accompanied by reasonable construction sequence.
