承载岸堤开挖与锚固支护有限元分析
|
摘要
通过对库区承载岸堤在开挖过程中锚固支护的有限元分析,计算了开挖工况和承载工况下岸堤的稳定性,并采用了有限元强度折减法分别计算了两种工况下相应的安全系数。采用有限元三维模型中的3-D接触类型,对承载岸堤开挖与锚固支护进行了数值模拟。
Through finite element analysis of anchoring support during excavation of the reservoir area loading bank,the bank stability of excavation operation and loading operation was calculated.The corresponding safety factors of the two operation states were calculated by the finite element strength reduction method.3-D contact type of finite element three-dimensional model was adopted to conduct numerical simulation of the loading bank excavation and anchoring support.
