真空预压侧向变形影响因素的研究
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、预压面积等因素对采用真空预压处理地基的侧向变形的影响进行了研究,并通过分析证明了巴隆轴对称固结理论单井假设的合理性。
Abstract:Based on a large number of data determined from the practical projects treated by vacuum preloading and the result of finite element analysis on the basis of Biot's consolidation theory,the factors including coefficient of consolidation, depth of the plastic drain, distance between the plastic drain, degree of vacuum and the preloading area, are studied which determine the lateral deformation of the foundation treated by vacuum preloading.The hypothesis of single well in Barron's theory of axially symmetric consolidation is also proved to be reasonable.
