| Study on dynamic response of circle-shaped tunnel liner buried in saturated soil under acting of harmonic annular loading |
| 摘要 |
| 基于Biot理論，研究了帶有襯砌的圓形隧洞在法向簡諧集中環(huán)形荷載作用下的動力響應(yīng)。假定襯砌為彈性體，土體為飽和多孔介質(zhì)，結(jié)合邊界條件及連續(xù)條件，通過傅立葉變換得到波數(shù)域中襯砌和土體的應(yīng)力、位移和孔隙水壓力幅值解答，最后用傅立葉逆變換得到動力響應(yīng)幅值的數(shù)值解。 |
