Crack Mechanism, Temperature Control, and Anti-Cracking Measures of Sluice

Abstract:

To address the problem of sluice concrete easily cracking during construction, this study introduces the crack mechanism of concrete structures. Temperature differences and constraints are the main causes of cracks. Anti-cracking measures should focus on optimizing concrete mixing ratio and improving construction technology. Using simulation calculation to model the actual construction process and temperature control measures, this study analyzes the causes of crack and selects timely and reasonable temperature control measures, which are necessary links in engineering construction. A three-dimensional finite element analysis was conducted for a huge concrete sluice structure. The causes of cracks are discussed, and timely and feasible anti-cracking measures are proposed to provide technical support for project construction.
