横观各向同性土体有限层分析

Finite layer analysis for a cross-isotropy homogeneous elastic soil

首先概括介绍了三维横观各向同性比奥固结有限层分析方法,并采用已经发表的 4 个算例结果来考证所编制的计算程序,然后详细地讨论了横观各向同性对瞬时沉降、最终沉降和固结性状的影响,发现横观各向同性对计算结果的影响分别高达 33 %,24 % 和 40 %,最后给出了一些对工程实践有一定参考价值的计算图表。

Based on the introduction of finite layer analysis for three-dimensional Biot's consolidation with a cross-isotropy elastic soil and the verification using four published results, the influences of cross-isotropy on the immediate settlement, the final settlement and the consolidation behaviour are discussed. It is found that the cross-isotropy has very large influences on the immediate settlement, the final settlement and the consolidation behaviour. The maximum differences are over 33%, 24%, and 40% respectively. In the end, curves or tables of the immediate settlement coefficients, the final settlement coefficients and the average degree of consolidation are obtained and presented in the paper, which is useful for engineering practice.
