开裂准则
During nonlinear calculation, according to the W-W five parameters failure theory, the fracture criterion of crack is established, the expansion of plastic range indicated that the cracks is dangerous for the dam's safety and the pier must be reinforced.
在非线性计算中,根据W-W的五参数混凝土破坏理论,建立混凝土的开裂准则。塑性区范围的扩大表明,现存裂缝对坝体安全性是有影响的,有必要对闸墩进行加固。
