Construction Simulation and Real-time Monitoring Research of Concrete Dam Based on BIM

Abstract

Concrete is a complex multiphase composite. Along with the hydration reaction, the thermal and mechanical properties of concrete continue to increase, resulting in deformations such as temperature, autogenous volume and shrinkage, and stress and creep after being restrained by themselves and externally, further cracks are formed. Through finite element simulation, the key parts of temperature control and crack prevention of concrete dam can be predicted, and targeted crack prevention measures can be proposed. Therefore based on BIM technology and combined with simulation results, this paper conducts real-time monitoring of concrete temperature and stress during construction. Through comparison and inversion analysis, the whole process dynamic management of temperature and stress during dam construction period is implemented, and temperature control measures are optimized in real time to realize the whole process control of temperature control and crack prevention of concrete dam.
