高性能混凝土冬季施工强度的线性回归分析

Linear Regression Analysis of Strength of High Per-formance Concrete Constructed in Winter Season

京津城际客运专线凉水河特大桥部分墩台需在冬季施工,结合工程实际通过对试验数据的线性回归分析,推导出高性能混凝土冬季施工强度的一元线性回归方程,以此指导施工。介绍回归方程的应用和适用条件。

Part of the piers and abutments of Liangshui River Bridge on Beijing-Tianjin Intercity Passenger Dedicated Railway have to be constructed in winter season. In this paper, with reference to the practical construction of the Bridge and through linear regression analysis of the relevant test data of high performance concrete, a one-variable linear regression equation for calculating the strength of the concrete constructed in winter season is deduced for guidance of construction, and the applications and applicable conditions of the equation are introduced as well.
