碾压混凝土有限体深埋裂缝应力强度因子计算方法试验分析

Calculating method and test analysis of stress and strength factor for deep fissures of roll compacted concrete finite boy

文章通过总结国内外文献并对照试验结果,对内设椭圆形预留缝的有限体混凝土应力强度因子的计算公式进行了修改,并对具有不同预留缝形式的混凝土试件的轴拉试验结果进行比较分析,推算出把带有矩形预留缝的混凝土试件简化成带有椭圆形预留缝的试件时的修正系数。

By means of summarizing internal and external documents and comparing experimental results, the calculating formula of stress and strength factor for concrete finite boy having ellipse fixed fissure in advance is revised. The axial elongation test results of test samples having different fixed fissures in advance are compared and analyzed. The revised coefficient of concrete test samples having rectangle fixed fissure simplified to ellipse fixed fissure is calculated.
