| Abstract: | The cracks easily occur in the course of the construction of the reinforced box culvert.The influencing factors include the temperature stress,the quality of raw materials,the uneven settlement of the foundation,the unstable support of the forms,the reinforcing bars of the structures,the vibrating of the concrete,and the poor curing,etc.In the light of the reasons of the cracks occurring on the sidewall of the drain box-culvert of a certain road section,the technicians modified the construction scheme and strengthen the monitoring and management of each link,avoiding the cracks. |
