| 摘 要： | 山地城市大量高层建筑建立在岩石地基之上,如何评价岩石地基的承载力是岩石地基工程的核心问题。文中考虑了中间主应力以及岩性、岩体结构特性对岩石地基承载力的影响,将非连续介质特性的节理岩体等效为连续介质,然后用即时摩擦角和滑移线场理论求解,建立了岩石地基极限承载力分析模型,并通过算例验证了模型的可行性。

| Abstract: | Many high-risie buildings are based on rock foundation in mountainous city,so how to evaluate the bearing capacity of rock foundation is the core for rock foundation engineering.In view of the influence of central major stress and lithology and rock structure characteristics on rock foundation bearing capacity,this paper equates jointing rock with discontinuous medium characteristics to continuous medium,and then seeks for solution with instant friction angle and slip-line field theory.It establishes analys... |
