The main problems of the pile are proposed by analyzing the pile data. The feasibility of making the pile meet the request of bearing capacity by grouting in the pile bottom is discussed. The idea on low strength request ( relative to the strength of the pile shaft ) to grouted body in sedimentary region at the pile bottom is clarified. The calculated settlement and horizontal displacement of the pile in the process of pushing execution is in accord well with measured result. The cause for fluctuation of measured settlement of the pile in process of pushing execution is also analyzed.
