高性能混凝土碳化深度的灰色系统理论计算模型

Grey System Theory-based Calculation Model of Carbonation Depth for High Performance Concrete

采用灰色系统理论计算模型GM(1,1)对8个高性能混凝土实体构件的碳化深度进行了建模计算,计算龄期分别为28,60,90,740 d和14年,并根据灰色模型模拟计算的误差变化规律,给出了非等间隔数据序列的转换、优化数据序列边界和优化数据序列参数等建模基本方法。将计算结果与8个构件实测碳化深度进行比较,验证了灰色系统理论计算模型的正确性和可行性。

Using the grey system theory-based calculation model GM（1,1）,the carbonation depth of 8 high performance concrete specimens were calculated.The calculation age was 28,60,90,740 d and 14 years respectively.Based on the error variation rule of the grey model simulation calculation, the basic modeling methods such as converting the non-equal interval data sequence,optimizing data sequence boundary and optimizing data sequence parameters were proposed. Comparing the calculation results with measured carbonation depth of 8 specimens,the correctness and feasibility of grey system theory-based calculation model were verified
