| Abstract: | In this paper the security assessment method of underground pipeline caused by the subway construction was studied,and analysis on the effect of measuring point spacing and measurement error in the pipeline deformation curvature calculation by three-point cyclic method was conducted,its applicability and related issues were discussed.The method of using six polynomial curve fitting to calculate pipeline deformation curvature was proposed,and combining with the engineering examples,its application was discussed. |
