摘要
在论述观测资料的常规分析,反演分析和反馈分析的基础上,应用变形观测资料,系统讨论反演混凝土坝和地基的物理力学■数(弹性模量、线膨胀系数、断裂韧度)、接缝(纵、横缝)的实际结构作用以及拱坝的实际拱梁荷载分配等的原理、方法及其应用研究。
The conventional,inversion and feedback analysis methods of observed data are discussed.Then the principles,methods and applicati ons of the inver- sion of observed displacement data are systematically studied.The inversion is mainly about the physical and mechanical parameters(Young′s modulus, linear expansion coefficient and fracture toughness)of concrete dams and the foundation,the real structural action of joints(longitudinal and transversal joints),and the real load distribution between the arch and the beam of an arch dam.
