Research on the Anti-Leakage System for Reinforced Concrete Flat Roofs in Cold Areas

To solve the persistent problem of roof leakage in cold areas, a reinforced concrete flat roof anti-leakage prevention system was proposed in this study, and the leakage prevention of this roof system in the cold areas was investigated by conducting a scaled-down model outdoor exposure test. In addition, the weather in the Harbin area during the freeze-thaw cycle season was predicted by the support vector machine (SVM) model in machine learning, based on which ABAQUS finite element analysis of the roof system was carried out to reveal the leakage prevention mechanism of the system. The research results show that improving the roof level temperature during the freeze-thaw cycle can reduce the influence of temperature stresses brought by the freeze-thaw cycle, slow down the development of cracks inside the roof, reduce the probability of roof leakage, and can provide a new idea for solving the roof leakage problem in a cold area.
