INSTALLATION TECHNOLOGY AND DEFORMATION CONTROL OF A HIGH-LEVEL LARGE-SPAN STEEL HOISTIING STRUCTURE

摘要

By project example analysis, in some special conditions that large crane can not be put in place and small and medium motocrane can not meet height and weight requirements to be installed due to regional limitations and restrictions of ground bearing capacity, mast hoisting construction method is put forward in this paper to solve this special hoisting problem successfully, simultaneously the project cost is reduced obviously, too. Results indicate that the method developed in this paper is simply applicable and it provides a significant reference for solving similar problem in real project.
