| 摘 要： | 根据弹性力学对地基中的球形土洞进行了分析,确定了最危险的关键点的应力状态,再利用莫尔-库仑准则判定其稳定性,指出土洞的3维球洞模型要比对应的2维圆孔模型更符合实际,而分析的结果表明,在相同条件下,球洞比圆孔不容易失稳.

| Abstract: | Stability analysis for a spherical cave in soil foundation was conducted based on the mechanics of elasticity. The stress condition for the key points in the most dangerous situation was established. Then Mohr- Coulumn criterion was used to estimate its stability. It is concluded that the threedimensional spherical model is more practical than the counterpart two- dimensional circular model for a cave in soil foundation, and the spherical cave is less easy to lose stability than the circular cave. |
