| 摘 要： | 随着大体积混凝土的广泛应用,混凝土的裂缝控制问题日益突出.裂缝的产生会导致混凝土的抗渗、抗腐蚀等性能下降,影响结构的耐久性.本文分析了大体积混凝土由于水化热而产生的开裂机理,结合实际工程,应用Midas软件模拟大体积混凝土温废场,重点解决了混凝士分层浇筑、水管冷却及边界条件等因素对其温控的影响,监测结果与理论分析较好吻合,论文研究工作对类似工程具有借鉴作用.

| Abstract: | With the widely application of the massive concrete,the problem of how to contr ol the cracks of the massive concrete have become more and more outstanding.Cra cks are always bad for the concrete's impermeability and anti-corrosion perform ance.This essay describes the mechanism of cracking in massive concrete,combine d with the actual project,using MIDAS software to simulate the temperature fiel d of massive concrete,via the simulation of hierarchical and blocking,cooling pipes,the boundary conditions and ... |
