The steel pipe column is the vertical load-bearing structure of top-down method, bored grouting pile is often used as its foundation. The bottom ends of the steel pipe piles were embedded in pile concrete to form the structural system with one column on one pile. Because of the vertical loads on this structural system, the requirements on the bearing capacity, verticality and settlement of the pile foundation are very strict. According to the problems of large diameter rock-socket revolving digging bored steel pipe columns construction under complicated geological conditions, this paper analyzes the different causes by examples and proposes prevention measures to ensure construction quality, which can be reference to similar project.
