Simultaneously, the thesis discusses the calculation theory and analysis method for beam on elastic foundation, and gives an in - depth discussion on each calculation model of beam on elastic foundation, including elastic theory model, wenker theory model, spring - system connected with flexible line model and double - foundation - bed coefficient model etc. the deficiency of elastic foundation finite element method of deep excavation timbering system presently is pointed out via the detailed investigation to the elastic foundation finite element method calculation theory and implement process based on wenker theory model
同時，本文論述了彈性地基梁的計算理論和分析方法，深入討論了彈性地基梁的各種計算模型，其中包括彈性理論模型、文克爾理論模型、用彈性柔線聯結的彈簧系模型、雙基床系數模型等。通過詳實地分析建立在文克爾理論模型基礎之上的彈性地基有限元法計算原理和實施過程，指出當前深基坑支護體系彈性地基有限元法的不足。
