with the great development of globalization, more and more high-rise buildings have been built up, accompanied by more and more foundation pit support and excavation. The forms of foundation pit support are more and more diverse, among which row pile support is widely used in engineering because of its mature construction technology and good supporting effect. However, it is difficult to directly measure the internal force of pile in engineering practice. In practice, the displacement of pile body is often monitored and the results are more accurate. In this paper, the method of spline interpolation function is used to measure the displacement of pile. The back analysis of the pile stress provides a reference for the application of pile structure in foundation pit.
