Aiming at the problems of horizontal displacement of tall and large buttressed dock walls，the low efficiency of formwork construction and the poor quality of concrete construction，we study the cast-in-place concrete buttressed dock wall in the dock project of the Dongfang Project，use the finite element analysis method to simulate the offset of the dock wall and set a 5 mm construction pre-offset，design tall and assembled integral wood formwork according to Technical Specification for Safety of Building Construction Formwork，heat old concrete by electric heating wire to reduce the shrinkage of new and old concrete and add pouring points. These measures meet the accuracy requirement that the installation error of the gantry crane track at the top of the dock wall gallery is not more than 5 mm，save more than 60 days of construction time for the dock wall structure，and reduce concrete constraint cracks and the occurrence of common quality problems such as honeycomb，hemp surface，gap interlayer and so on. The research has certain reference significance for the construction projects of similar tall and large dock wall structures.
