In order to discuss the winter construction quality control technology of pier structure in north area of China,taking the working pier of Tianjin wharf project as the prototype,according to the proposed winter construction scheme,the scale physical model test was carried out.Through the comparative analysis of the monitoring data of the test block temperature field and the finite element calculation results,feasibility of finite element temperature field analysis and rationality of index selection was verified.On this basis,through the analysis of pier temperature distribution influence based on the thermos method,comprehensive conservation method and circulating cooling system,the optimal construction control technology for winter construction of pier was put forward.
