Methods for ensuring the required consumer properties for the construction of transport facilities in an accelerated time frame

The article discusses methods for providing concreting of transport objects without defects using the example of the construction of a bridge across the Kerch Strait. It is shown that through the use of modern calculation and analytical methods, it is possible to obtain high-quality structures and operational reliability under the conditions of the necessary construction pace. These methods are based on the construction of a thermophysical model of the processes that occur in hardening concrete during heating and cooling. The existing experience in the construction of similar facilities is also taken into account. The problem posed today is relevant in connection with the development of bridge building in our country. It has important economic and geo-political significance, and its solution is not possible without taking into account the temperature factor of hardening concrete. The proposed methods made it possible to ensure the required operational properties of the structures of this type and to withstand the established deadlines for the construction of the Crimean bridge. They can be used in the construction of other objects of this type.
