【摘要】 进行了在碳化箱中加速腐蚀碳化环境状态下的混凝土结构碳化试验,试件为直接受压的应力状态,阐述了试验中采用休哈特控制图对碳化深度数据进行采集和动态统计控制原理,建立了压应力状态下碳化深度动态统计控制模型。试验结果表明,该方法能有效的对钢筋混凝土结构在压应力工作状态下的碳化深度进行动态监测、分析、评价和控制,避免对结构的耐久性及稳定性产生不利影响,造成安全隐患,从而确保在承载环境中钢筋混凝土结构的质量和安全。更多还原

【Abstract】 The concrete carbonization tests under the environment of accelerated corrosion in carbonation tank were carried out. The specimens were in the state of direct compression stress. Hugh-hart control charts were used in test of carbonation depth data acquisition and statistical control principle,and the carbonation depth dynamic statistical control model under dynamic compressive stress state is established. Experimental results show that this method is effective in dynamically monitoring,analysing,evaluating and controlling the carbonation depth of reinforced concrete structure under the working condition of compressive stress,then the adverse effect on the durability and stability of the structure and the potential safety hazard is avoided to ensure the quality of the reinforced concrete structure in the hosting environment and security.更多还原
