特高拱坝一级变形预报控制值建立的方法研究

Study on method of establishing primary deformation prediction control value for super-high arch dam

特高拱坝与一般高拱坝相比,其结构性态更加复杂,因此,其变形安全预报控制值必须进行专门的研究。文中探讨了特高拱坝的定义与特点,分析了特高拱坝的变形特性,提出了特高拱坝一级变形预报控制值建立的准则与方法。工程案例表明,该方法切实可行。

Compared with the conventional high arch dam, the structural behavior of super-high arch dam is more complicated, and then, special study must be made on its deformation safety prediction control value. The definition and characteristics of the super-high arch dam are discussed herein, furthermore, the deformation behavior of the dam is analyzed as well; from which the criteria and method of establishing the primary deformation prediction control value for the dam are put forward. The relevant actual engineering case shows that this method is feasible in the practice.
