PRACTICAL DYNAMIC ANALYSES OF EARTH DAMS BY A SIMPLIFIED 3-D METHOD
|
抄録（英）：
A practical method is presented for dynamic analysis of three dimensional earth dams in any shaped canyon by extending the conventional shear beam theory. A dam is represented as a configuration of prismatic finite elements whose elastic modulus varies as arbitrary power of depth below the crest. Mass and stiffness matrices of the element are explicitly given in terms of coefficient of power of depth. With an equivalent nodal force vector formulated for simulation of forced vibration tests as well as for earthquake response analysis, the method is applied to case histories of existing dams. Comparisons between the analytical results with the observations demonstrate validity and practicability of the method, and provide important findings on dynamic behavior of earth dams.
