自从太沙基(K.Terzaghi)发表了著名的粘土固結理論以后,很多研究者对此問題曾給以很大的注意,并取得了不少宝貴的成果。近年来,陈宗基、弗洛林、比奥(M.A.Biot)等进一步提出了考虑到粘土流变性貭的理論。陈宗基氏并依据把粘土当作一种馬克斯維尔体(Maxwell body)的簡化假定,导出了若干公式。但其計算过于复杂,以致难于用它来解决实际工程問題。本文提出了一个实用的近似解法,并給出了各种边界条件下单維問題的解答。該法的出发点是:把全部变形分成体积变形和畸变变形两部分,分別求算而后迭加。
Since K. Terzaghi published the famous theory of clay consolidation, many researchers have given great attention to this issue and have achieved many valuable results. In recent years, Chen Zongji, Florin, M.A. Biot, etc. have further proposed the theory that considers the rheological behavior of clays. Chen Zongji derived several formulas based on the simplified assumption that clay is a Maxwell body. However, its calculations are so complicated that it is difficult to use it to solve practical engineering problems. In this paper, a practical approximate solution is proposed and the solutions to the single-dimensional problems under various boundary conditions are given. The starting point of this law is: The whole deformation is divided into two parts of volume deformation and distortion deformation, respectively calculated and then superposed.
