Therefore, construction method of bored piles is investigated necessarily. Firstly, this paper investigates deeply the key construction factors which affect the loadbearing capacity of bored piles. Construction method of bored piles is investigated based on practical projects and quality control system is put forward. In view of the quality accident reason of piles construction, some measures are also put forward. At last, on the basis of the a reservoir bridge practice, the methods for disposing of construction method and engineering accident are given and summarized, Which would be the usefu
