With the prominent contradiction between urbanization acceleration and land resource scarcity,the application of collinear continuous viaducts in the expressway is more and more widely.Based on the construction of large cantilever prestressed bent cap with few brackets method in the collinear section of Keqiao-Zhuji Expressway engineering,this paper expounds in detail from the aspects of bracket design and optimization,bracket erection construction technology,and main safety measures,so as to minimize the influence of construction on existing road traffic and achieve the purpose of safe and rapid construction.
