摘要:
在黏弹性介质地基的比奥固结和基坑开挖问题有限层求解格式基础上,运用Laplace逆变换,编制了黏弹性介质地基位移计算的比奥固结和基坑开挖问题有限层求解程序,通过计算黏弹性地基沉降的算例,验证了计算方法与程序的正确性, 随着黏滞性系数的增加,该模型的黏性起到更大的作用,符合所选取黏弹性模型的蠕变变化规律.
Abstract:
Based on the calculation method for finite layer analysis of Biot′s consolidation and excavation of viscoelastic soil, the calculation algorithm for finite layer of Biot′s consolidation of viscoelastic soil was programmed by Laplace retransformation. Example analyses of viscoelastic foundation verified the calculation method and the program. With the increase of viscocity coefficient, the viscidity of the material is enhanced. This is in fine agreement with the creep rule of choosen viscoelastic model.
