| 摘 要： | Love波的传播特性对动力响应和工程勘探都具有重要意义。运用解析法建立了交通荷载作用下双层地基中Love波的特征方程和位移表达式,并对方程进行了求解,得到了不同交通荷载情况下地基中Love波的弥散特性和位移分布情况。结果表明,交通荷载作用下Love表面波的传播速度不仅与土层的剪切波速度有关,而且与土层的压缩波速度有关。

| Abstract: | The characteristics of Love wave induced by vehicle loads are of tremendous importance to both dynamic response of structure and exploration of the soil profile. Analytical method is applied to construct the displacement distribution equation and the dispersion secular equation of Love wave generated by vehicle loads in two-layered ground. The dispersion characteristics and displacement distribution of Love wave under various loads are discussed. The results prove Love wave induced by vehicle loads is different from the Love wave induced by other loads; the properties of Love wave generated by vehicle loads are not only related to the thickness,mass density and shear wave velocity of the layer soil,but also related to compression wave velocities in soil. |
