摘要
针对上海地铁车站的开裂渗漏问题 ,分析了大体积混凝土的温度收缩应力对开裂的影响 ,得到了适用于地铁车站结构的温度收缩应力、裂缝间距、裂缝宽度的计算公式 ,在技术上提出解决开裂问题的思路 ,并结合工程实例 ,用计算结果论证了所提方法的可行性。
According to crack and leakage problems of Shanghai subway stations, authors analyze the influence of temperature shrink stress of large volume concrete on cracking, and deduce such calculation formulas applicable for temperature shrink stress, crack separation and width of subway station structures. Authors also provide a technical method to solve the crack problem, and prove the feasibility of the method with calculation results of a practical example.
