中文摘要：
对失稳断裂韧度的尺寸、边界效应及有效裂纹扩展量开展深入探讨,研究不同尺寸非标准试件之间的失稳断裂韧度尺寸、边界效应和反映实际规律且具有实际物理意义的有效裂纹扩展量,基于上述讨论,建立考虑上述影响因素的单向间隔诱导缝等效强度模型,同试验结果对比发现,模型具有较好精度,可作为大体积混凝土单向间隔诱导缝等效强度的推荐公式。
英文摘要：
Unstable fracture toughness is used to analyze size,boundary effect and crack propagation of concrete.Both size effect,boundary effect formula for unstable fracture toughness and crack propagation formula with real physical meaning and realistic rule are presented.Based on which,formulas for predicting the equivalent strength of unilater interval induced joint are proposed,in which these coupling effects on the equivalent strength are considered.The comparisons of the predictions given by the present model with experimental data prove that the model of the paper is efficient and accurate.
