The beam - on - dynamic - winkler - foundation ( bdwf ) model was utilized to determine the lateral dynamic response of a pile with finite length in a viscoelastic soil. an analytical solution was obtained in the time domain for the vibration of a pile under a laterally cyclic force applied at the pile head. based on the solution, the transient response of the pile loaded by semi - sine force was acquired with superposition principle
首先，基於動力winkler模型（ bdwf ）對粘彈性地基中有限長樁的水平動力響應問題進行求解，得到了單樁在樁頂受水平簡諧荷載作用下的時域解析解，並在此基礎上通過疊加原理得到了半正弦激振條件下的瞬態解析解。 -
