摘要

In the present paper, an attempt is made to monitor the behaviour of steel pipe pile on clayey slope while excavating for a basement of a building. The basement excavation is supported by RCC diaphragm wall, which gets the lateral support from temporary steel pipe piles to enable top-down construction in the peripheral area, which are connected to the diaphragm wall with basement floor slabs. The horizontal displacement of the piles is measured based on inclinometer tubes embedded in the diaphragm wall. A detailed finite element analysis has been carried out using PLAXIS 3D model and the theoretical results are compared with the field observations.
