| On bearing capacity of pile foundation as well as the stability is better than other foundation forms,so the roads and Bridges,high-rise and high-rise buildings,other engineering areas such as application is very widespread.With the continuous development of China's urbanization con-struction,the theoretical research and construction methods of pile foundation have obtained cer-tain development.The application of pile foundation can be seen in many projects,and there have been many diflferent kinds of piles,such as steel pipe pile,steel concrete pile,steel pipe concrete pile,etc.In this paper,the design method of pile foundation under vertical load is sum-marized,and the foundation design and numerical simulation of south square pile of xiangtan tianyi sports park are carried out through this design method.The specific work is as follows:1?Find the literature related to pile foundation at home and abroad,and systematically classify the pile foundation according to the characteristics of pile.This paper summarizes the research of pile foundation test,theoretical research,pile foundation design research and current pile foundation research.2?The design method of pile foundation under vertical load is summarized,and the general principles and basic steps of design of pile foundation design are discussed.Based on the sum-mary design method,the pile foundation design was carried out for the south square project of xiangtan tianyi sports park,and the construction drawing of pile foundation was obtained.3?The numerical simulation is carried out on the pile foundation of the design,and the settlement value calculated by the design is compared with the settlement value calculated by the numerical simulation,and the correctness of the pile foundation design is verified.The ultimate bearing capacity of pile foundation is determined by the Q?s curve obtained by numerical simulation,and the mechanical mechanism of single pile under vertical load and the parameters of pile group are analyzed. |
