The study discusses the influence of three different pylon-strut systems with the position of strut and the initial force on the linear control of curved bridge tower comprehensively with the indexes of stress,displacement and construction difficulty,etc.The construction of bridge tower adopts the simultaneous construction of jacking bracket to monitor the transverse support force in real time.The influence of gravity and temperature on the linear shape of the curved bridge tower must be considered in the process of pouring,and the linear shape of the bridge must meet the design by setting the pre-arch degree and cross bracing.The construction support scheme of bridge tower beam should be optimized,and the reasonable support scheme should be determined by the comprehensive influence of displacement and stress.The stability and construction feasibility of the pylon-cross support system meet the actual needs,and can provide technical support for the smooth construction of bridge pylon.
