混凝土断裂研究中预制裂缝影响探讨

Discussion on effect of precast crack in fracture research of concrete

对混凝土断裂试验中预制裂缝作了研究,通过比较分析两组试验数据及另一组试验现象,探讨了预制缝对试件扩展的影响,得出了一些结论,为类似问题的研究奠定了基础。

Precast crack of concrete in fracture test were discussed simply.Effect of precast crack of concrete to crack propagation were discussed by comparison of two sets of test results and analysis of other experimental phenomenon,drawn some conclusions,laid foundation for the research of same kind of problem.
