摘要
将力学模型引入大坝安全监测领域 ,结合变形监测资料 ,提出利用三维粘弹塑性大变形理论拟定混凝土坝三级监控指标的原理和方法 ,并拟定了龙羊峡大坝变形三级监控指标 ,取得了安全监控大坝的实效 .
On the basis of deformation observation data and the application of mechanical models in the field of dam safety monitoring,presented in this paper are the theory and method of determining grade three monitoring indicator for concrete dams with the three dimensional visco elastic plastic large deformation theory. By use of the theory and method, the grade three indicator of Longyangxia dam is successfully determined.Example shows that the results are satisfactory.
