single stratum
解釋
單層-
Novak layer method is introduced to obtain the vertical dynamic impedances of both an end - bearing pile and a floating pile in a homogenous stratum. and the vertical dynamic impedances of single pile are analyzed in homogenous elastic soil, inhomogenous viscoelastic soil homogenous viscoelastic soil. at the same time, the factors to influence the impedances of single pile are examined
本論文採用novak薄層法，推導了在均質地基中，端承單樁和摩擦單樁的動阻抗；並全面分析和對比了均質彈性、均質粘彈性和非均質粘彈性地基模型中的單樁的動力阻抗，考察了各種因素對單樁動力阻抗的影響程度。 -
With synthesize slope ratio increasing, the stability of cutting slopes decreases, but the stability of sharpen slope affected by natural slopes ratio changes rarely, the stability of cutting slope that height is 30m is change notably due to slope type, whose single slope ratio with madao is inferior to the slope that upper ratio is less than lower ratio with platform in middle part. but the stability of cutting slope with 50m height is little change with the slope type change. with same stratum, slope height, slope type, the cutting slope is inferior to the sharpen slope in stability
結果表明，地層含水量在12 . 0 18 . 0變化范圍內，各種挖方邊坡穩定性均隨濕度的增大而顯著降低；路塹邊坡的穩定性隨綜合坡比的增大而降低，但削坡受自然坡比影響，隨綜合坡比的增大其穩定性基本不變；坡高30m的路塹邊坡穩定性因坡型改變而有明顯變化，且單一坡比多級馬道型邊坡的穩定性較上緩下陡平臺型邊坡的穩定性差，但坡高50m的路塹邊坡穩定性因坡型變化而基本不變；當坡高、坡型、地層條件相同時，路塹邊坡的穩定性較削坡的穩定性差。 -
