摘要
在混凝土结构中打入锚杆进行加固时,采用三维块体单元和杆单元结合的有限元网格模型相对较复杂,且计算模型也较复杂。以松山引水工程溢洪道闸墩锚固为例,简化了有限元网格模型,只采用三维块体单元,而忽略了杆单元,杆单元用一对方向相反、大小相等的钢筋屈服力来代替,计算结果良好。
When setting anchor in the concrete structure reinforcement,it is a common practice to adopts finite element analysis method which combines three-dimensional block element and bar element in calculation,therefore not only the establishment of finite element mesh model is relatively more complex,but also the calculation model is also more complex.Taking spillway pier of Songshan diversion project for an example,the finite element mesh model is simplified and the finite element mesh model adopts only the three-dimensional block element,ignoring bar element.The bar element consists of a pair of steel yield force which is in the opposite direction and the same size instead,the calculated results are good.
