| 摘 要： | 针对某混凝土楼盖在养护期发生冻害现象的实际工程案例,本文对受冻混凝土楼盖使用性能进行了分析与计算,最终提出了用置换受压区混凝土并增设＂暗梁＂的整体式补强方法加固楼板.使用该方案加固后的建筑物,投入使用2年多未发现任何问题,加固效果良好.

| Abstract: | Based on the construction case of frost damage for concrete slab during coagulation,the paper analyses and Calculates the freezed concrete slab,and integral strengthening by replacing compressive concrete and adding hidden-beam was put forward.There's noproblem which has taken place for more than two years since they were put into use,which shows that the reinforcement has achieved good result. |
