Research on Construction Technology of First Pile in an Urban Expressway under Complicated Conditions

[摘要] This paper develops a research method on the construction of the first pile in the process of the construction on an urban expressway under complicated conditions, such as the difference between the underground conditions and the exploration results,the sand formation,the whole weathered and the rich groundwater. We study the relevant technical parameters and construction organization through construction of the first pile. The results show that construction on the first pile is very important under complicated conditions and can provide a basis to continuously improve the level of the whole pile foundation construction technology, and ultimately determine the entire project feasible construction program and the successful completion of the construction project.
