摘要
介绍了点荷法和筒压法检测砌体砂浆强度试验,用现行规范换算强度与同盘标准抗压强度比较,采用最小二乘法原理以5种函数对试验数据进行拟合,得出与标准抗压强度的函数关系,从而将检测强度转化为标准抗压强度,为两种检测方法强度比较建立联系。
Experiments were done on mortar with the methods of column compression and point load,and then to compare the conversion intensity and the standard compressive strength.The principle of least squares method and five kinds of function form were adopted to regression analysis of data in order to be a function.Comparison of two detection methods intensity was set up links to reduce the detection error by detecting the intensity into a standard compressive strength.
