| 摘 要： | 为了研究强夯作用下土石混合体填筑边坡的动力特性,以昆明新建机场土石混合体填筑边坡为研究对象,采用现场试验和数值模拟相结合的方法研究其在强夯过程中位移变形和振动加速度.结果表明:变形主要发生在边坡的中上部,最大变形量发生在坡顶,边坡底部基本检测不到变形量;强夯引起的振动影响与边坡坡度成正比,坡度大的边坡振动影响大,坡度小...

| Abstract: | Focused on the soil-rock mixture filling-up slope of Kunming new airport,the field test and numerical simulation were applied to study the displacement and vibration characteristics of this kind slope under dynamic compaction.The results showed that the distortion mainly appeared in the upper and middle section of slope,and the maximum displacement appeared in the top of slope,but almost no displacement appeared on the bottom of slop.And the vibration influence is proportional to the degree of slope.That is... |
