摘要
依据大量工程实测资料以及以比奥(Biot)固结理论为基础的有限元分析结果,对固结系数、排水板打设间距、真空度、预压面积等因素对真空预压处理地基的侧向变形的影响进行了研究,通过分析证明了巴隆轴对称固结理论单井假设的合理性。
Based on a large number of real-surveyed engineering data and the result of finite element analysis on the basis of Biot's Consolidation Theory,this paper carried out a study on the influence of the factors such as coefficient of consolidation,driving space between plastic drain plates,degree of vacuum and preloading area,etc.on the lateral deformation of foundation treated by vacuum preloading method,and proved that the hypothesis of single well in Barron's theory of axially symmetric consolidation is reasonable.
