Abstract
With the increasing number of high-rise buildings,the application of large volume concrete raft foundation is becoming more and more widespread,and its temperature stress and crack control have become key research areas.This article uses Midas FEA software to analyze the temperature stress of large volume concrete,and verifies the accuracy of theoretical analysis with on-site measured data.The research re-sults indicate that hydration heat and environmental factors are the main factors affecting crack formation.This article proposes control measures such as optimizing concrete mix proportions,insulation curing,and temperature monitoring to reduce crack risks,and provides theoretical basis and technical support.关键词
