本文应用染色法,并配合声发射法与应变法等,对在瞬时荷载下混凝土裂纹的扩展进行了研究,探讨了在达到极限荷载前混凝土的断裂行为和机理,证明了混凝土裂纹并不存在亚临界扩展。
In this paper, the dyeing method and acoustic emission method and strain method are used to study the crack propagation of concrete under transient load. The fracture behavior and mechanism of the concrete before reaching ultimate load are discussed. It is proved that the concrete crack does not exist. Critical expansion.
