摘　　要：为了对聚乙烯醇纤维水泥复合砂浆强度检测方法进行研究,参照混凝土强度检测方法,选定后装拔出法对聚乙烯醇纤维水泥复合砂浆强度检测方法进行试验研究。结果表明,聚乙烯醇纤维水泥复合砂浆抗压强度与后装拔出力呈线形关系。通过线形回归分析,利用最小二乘法拟合直线,拟合回归方程有着较高的精确度。In order to research a method for detecting the strength of polyvinyl alcohol fiber cement mortar,based on the test method of concrete strength,the pull-out post-insert method is selected for experiment.The result demonstrates that there is a good linear relationship in the compressive strength of polyvinyl alcohol fiber cement mortar and pulling out post-insert force.By the regression analysis and the fitted line by the least square method,the fitted regression equation has a higher accuracy.
