通過屈曲理論分析結果對比表明，彈性屈曲和突變失穩分析的結果比非線性屈曲分析的結果要大得多，非線性分析由於考慮了材料非線性和幾何非線性，因而結果與實際接近實際；當只有初期支護時，隨著地應力的增加，圍巖的荷載分擔率增大，相應地，初期支護的荷載分擔率就減小了；當有初期支護和二次襯砌共同作用時，圍巖的荷載分擔率在50以上，這一分擔率隨地應力的增加其變化不大；支護和巖體的整體分析表明，襯砌底拱及拱腳處應力集中嚴重，隧道巖體側墻及墻角圍巖的應力集中也較大。By adopting the calculating analysis method of elastic - plastic three - dimensional fem numeric simulation, this paper makes a simulation analysis on the structure stability of the shallow cover and unsymmetrically loaded parts in tongyoushan tunnel, mainly simulates the effects caused by different construction orders on surroundings and supporting structure stability, and it centers on the analysis on the weak part, the midwall in the lining of the connecting - arch tunnel
