The settlement values of a practical ancient building were calculated through the simplified calculation formula to analyze the influence of pile foundation of high-rise building on adjacent structures. The feasibility of the formula was verified by comparing the calculation results of settlement with the practical monitoring results. According to the engineering example, FEM numerical simulation of the incidence of raft and pile length to surrounding buildings was performed. The feasibility and correctness of numerical simulation were also verified by comparing the simulation results to the measured values. The research results provided a reliable basis for the construction of Jinan Shimao Plaza, which could give technical reference for similar geological conditions %K 高层建筑 %K 桩基 %K 施工监测 %K 沉降分析 %K 有限元数值模拟 %K < %K br> %K construction monitoring %K settlement analysis %K finite element modeling numerical simulation %K high-rise buildings %K pile foundation %U http://gxbwk.njournal.sdu.edu.cn/CN/10.6040/j.issn.1672-3961.0.2016.195
