In the most of the cold regions of the Northern Hemisphere, three even six months are cold season every year. In order to meet the needs of the project schedule, a large number of construction engineering are still advanced in winter. The low temperature can cause cast-in-situ concrete component of early frost, greatly reduce its safety and durability, therefore, must be on the winter concrete engineering to take corresponding measures to ensure the smooth construction of concrete. It is necessary to extend the protection period. However, it had better finish the course of concrete construction quickly to the Top-Down construction method. This is a contradiction which is very difficult to solve. This paper points out the characteristics of concrete engineering construction in winter, describes the basic principles and methods of concrete engineering construction in winter and the characteristics of the deep foundation pit by Top-Down construction method, and discusses this contradiction about the speed of concrete construction. At last, this paper gives the technical measures and management measures to solve this problem. Through the research of this paper, some meaningful conclusions are received, which can provide the reference for the other constructions.
