摘　　要：本文发展了考虑半透水下卧层的未打穿竖井地基固结解析理论 ,并分析了此类地基的固结基本形状。研究表明 ,半透水边界对竖井地基固结过程有较大影响 ;下卧层半透水综合参数 Rv 越大 ,固结越快 ;当其增大到一定程度时 ,其影响可忽略 。The paper develops the analytic theory of ground consolidation bb shaft of un-striking through semi-permeable down horizontal bed. And it analyses the basic consolidation shape of this kind of ground. The study states clearly the semi-permeable boundary has a greater influence on the ground consolidation course by shaft. The more the semi-permeable comprehensive parameter Rv of down horizontal bed is, the rapider the consolidation is. When it increases to a certain degree, the influence could be neglect, i.e. the semi-permeable boundary could be treated as complete permeable boundary.
