Secondly , around the present research situation about the interaction analysis of structure and foundation , this dissertation gives a detail review . based on the 3 - d non - thickness jointed element theory , a new model is proposed which simulates the tangential slip effect of the jointed face . by means of increment loads searched automatically methods , the program is achieved to validate the feasibilities of the model 其次,本文對結構和基礎的接觸問題研究現(xiàn)狀進行了回顧分析,并在“空間無厚度接觸單元”的基礎上,提出了模擬接縫面切向滑動的本構關系,采用“變增量搜索法”進行計算,通過算例分析得到了該模型的合理性、實用性驗證。
