摘　　要：利用静态应变仪及分析软件在混凝土抗压强度试验时对混凝土试件产生的横向变形数据进行采集和分析,得出沿混凝土试件高度范围内,距压板越远,环箍效应对试件的影响越小,反之亦然。环箍效应对混凝土试件的影响集中在距压板√3/2 a范围内。This paper collects and analyzes the transverse deformation data of concrete specimens in compressive strength tests using static strain gauge and analysis software.It is found that within the height of the specimen,the farther away from the compression plate,the smaller the influence of hoop effect on the specimen,and vice versa.The influence of 3 hoop effect on concrete specimen is concentrated within a range of √3/2 a from the compression plate.
