(機械工業(yè)部第四設(shè)計研究院 洛陽 471039)[提要] 本文由彈性半空間的波動理論,導出天然地基動力剛度系數(shù)理論公式。求得的各向動力剛度系數(shù)之間的關(guān)系與頻率及土類有關(guān),并非固定值。理論結(jié)果與實測值甚為吻合。
[關(guān)鍵詞] 天然地基 動力剛度 彈性半空間According to wave theory of elastic half-space, the formula of dynamic stiffness in natural soil is given.
It is proved that the relation between dynamic stiffness coefficients along various direction is not unchanged, but related to frequency andthe kinds of soil. The theory result coincides the test data well.
Keywords: natural soil; dynamic stiffness; elastic half-space
