本文采用横观各向同性层状粘弹性模型模拟半空间之上的层状场地,用阻尼器取代其下部的半空间以吸收振动能量。在求解该场地对环形简谐荷载的响应时,采用薄层元素法导出满足上述边界条件的离散化后的自由振动方程,利用与Kausel等人的正交条件对应的求规格化特征向量的方法,给出了有关系数的计算公式。最后给出了横观各向同性层状场地对环形简谐荷载响应的一般形式。
In this paper, the transversely isotropic laminar viscoelastic model is used to simulate the layered field on the half space, and the damper is used to replace the lower half of the space to absorb vibrational energy. In order to solve the response of the site to the toroidal harmonic loads, the thin-layer element method is used to derive the discretized free vibration equation that satisfies the above boundary conditions, and the normalized eigenvectors corresponding to the orthogonal conditions of Kausel et al. are used. The calculation formula for the relevant coefficient is given. Finally, the general form of the response of a toroidal cyclic load on a transversely isotropic layered site is given.
