| 摘 要： | 总结了承压水基坑既有突涌稳定分析方法,分析每种方法存在的不足.最后分析指出,软土地区承压水基坑抗突涌稳定分析,应从坑底土透水性和土体发生突涌破坏的机理着手.坑底为不透水层土时,应从土体发生突涌塑性破坏的角度进行分析;坑底为弱透水层土时,应从土体发生突涌渗透破坏的角度进行分析.

| Abstract: | The existing calculation methods of inrushing for confined water foundation pit are summarized,and their shortcomings were analyzed.In the end,this paper suggests that,the anti-inrushing stability of confined water foundation pit in soft soil area should be analyzed from perviousness and inrushing mechanism of soil at the bottom of the pit.For impervious layer,the anti-inrushing stability of the pit is analyzed from the plastic damage of soil,but for semipervious layer,the anti-inrushing stability of the pit is analyzed from the seepage damage of soil. |
