摘要
本文对循环荷载作用下双层地基一维团结作了研究．基于Ｔｅｒｚａｇｈｉ假设，利用Ｌａｐｌａｃｅ变换推导了任意荷载作用下一维固结方程的通解，并对特例情况下几种常见循环荷载下地基有效应力和沉降的解析算式作了详细推导，经典Ｔｅｒｚａｇｈｉ一维固结理论解是本文的一个特例．文中给出了算例分析并对所得解答作了有益的讨论，提出了进一步研究的内容．
One dimensional consolidation of double-layered ground subjected to cyclic loading is considered in this paper. The consolidation equation for time-dependent loading is directly solved by means of Laplace transform and a general solution is derived in terms of integration. Based on the general solution,analytical solutions of the double-layered system under step loading,square and triangular cyclic loadings in a special case are obtained by use of the inverse transform. Terzaghi's one dimensional consolidation theory is only a speciality herein. In addition,numerical examples and valuable discussions on the solutions are presented.
