Abstract

The mechanism of crack formation on the concrete structure of gate piers during the construction period is analyzed. The temperature control and cracking prevention technique which combines surface heat preservation and the installation of expansion reinforcing bands is proposed. Based on the calculation principle of temperature fields and stress fields of concrete structures, simulated calculation analysis is conducted on the gate pier structure during the construction process by using the finite element method. The results show that the crack prevention effect of this temperature control measure is positive, and this measure has a certain reference value to similar engineering designs and constructions.
