Abstract Abstract : Research purposes ： According to the area environment characteristics of Beijing and process characteristics
of hole - pile method，this paper aims at the construction shaft setting mode，cross channel setting mode，pilot tunnel
design，steel pipe pile design，buckle arch design for a systematical study of hole - pile method，further explores the
hole - pile method application of boundary conditions in terms of design，further researches to explore the key technology and key measures in design and construction of beijing subway station， sums comprehensive technical guidance of the hole - pile method up，in order to provide a reference for future similar metro engineering construction.
Research conclusions:(1) The main idea of hole - pile method is forming vertical bearing structure as soon as possible. (2) Hole - pile method has the advantages of flexibility，good adaptability，which is suitable for the undercut subway
station construction under complex environment. ( 3 ) Systematic research of hole - pile method design and construction is hysteretic，which needs to be further researched. (4) The results of this paper can provide reference for the subway
station design with hole - pile method under complex environment.
