摘要 建立了倒虹吸结构与地基相互作用的三维节理元模型,并采用结构化程序设计方法,编制了三维节理元计算软件.通过计算与分析,描绘出了接触面上的应力,较好地解决了倒虹吸的相互作用问题. The interaction of the inverted siphon of diverting water from south to north and the foundation was studied. As material character of the inverted siphon was very different from that of the foundation, on certain condition slide or split would happen on the contact face. To reflect the character of contact face, a special joint element should be adopted. A three dimensional joint element model of the interaction was established. The structured programming technique was adopted and the program about three dimensional joint engineering practice was developed and the interaction problem of the structure and foundation was well solved, which provided the sufficient theory base for the safety design of the inverted siphons.
