摘要
基于比奥固结理论,采用邓肯-张非线性弹性模型,对基坑开挖过程中的应力场与渗流场进行完全耦合分析,研究了基坑工程的时间效应和空间效应。对基坑开挖过程中的基坑变形进行了全面深入的研究,探讨了基坑变形的分布规律,为基坑工程的设计和施工提供了理论基础。
Based on Blot＇ s consolidation theory and Duncan - Chang＇ s non - linear elastic model, the coupling of stress field and seepage field was analyzed during excavation, and the time and spatial effects of excavation were investigated. Deformations induced by excavation were studied systematically and thoroughly, and their distribution rules were obtained, which provided theoretical basis for design and construction involved with excavation.
