RESPONSE OF SINGLE PILE EMBEDDED IN TRANSVERSELY ISOTROPIC STRATIFIED STRATA TO INCIDENT SH WAVES
TI层状场地中单桩对入射SH波的响应分析

A model of transversely isotropic stratified strata is used to simulate the soil layers. At the bottom of the strata,dampers are used to absorb the vibration energy. A pile is embedded in this strata. The method for calculation of the dynamic impedance of single pile is developed. Combining the impedance and the response of the strata to incident SH waves,the response of single pile is obtained. The numerical examples indicate that the maximal moment of pile may cause the pile to fail,and more attention should be paid to the phenomena.
