【摘要】 陀螺桩是一种新型的地基基础形式,本文以天津地区典型地基为例,运用有限元方法计算了三种不同基础下的土体应力分布和地基表面沉降。通过比较分析,认为陀螺桩基础能够改善地基土体附加应力的分布,使其更加均匀,并增加应力扩散,从而有效地减少地基沉降,提高地基承载力。更多还原

【Abstract】 Top-shaped concrete block foundation is a new foundation structure.The FEM is used to analysis the stress distribution and ground subsidence of the soil under three different foundation structures.By comparing the calculation results,the conclusion that the top-shaped concrete block foundation can improve the stress homogeneous distribution and reduce the ground subsidence is drawn.更多还原
