Abstract
Taking the construction of the main bridge tower of an extra-large river-crossing bridge as an example,this paper adopts closed hydraulic climbing form for the main tower,support method and bracket method for upper and lower crossbeams,stage pouring of tower column and so on from the point of view of key difficulties and safety in construction.Its construction technology is complex,overcoming many important and difficult influences and comprehensive coverage.Through the summary and exposition of the key technologies of the main tower construction,the concrete technology and process of the main tower construction are introduced in detail.The purpose of this paper is to provide reference for the optimal design of similar projects.关键词
