Abstract: Based on the measured data of the pile foundation engineering in Tianjin Binhai, some programs for the settlement calculation of a pile foundation are compiled by MATLAB software, the settlements of the pile-pile cap foundation are respectively calculated by the summation method of an equivalent effect in layers and the equivalent entity deep foundation method, and the settlements of the piled raft foundation are calculated by Mindlin method. The analysis shows that the settlements calculated by the summation method of an equivalent effect in layers are smaller than its measured values, while the calculated settlements of the equivalent entity deep foundation method and the Mindlin method are all larger than their measured values. The analyzed results will provide a reference for the application of this three settlement calculation methods for the pile foundation in Tianjin Binhai.
