利用修正太沙基理论进行土体非线性固结沉降计算研究

Study of the amended Terzaghi theory in calculating clay's non - linear consolidation

提出在基于小变形弹性假定的太沙基-维固结方程解答中采用非线性条件下定义的固结系数,并且进行了计算验证,结果证明在小变形弹性固结方程的解答中采用非线性条件下定义的固结系数可以使计算结果更好地接近实际沉降值。相对于传统太沙基理论,修正后的太沙基固结理论可以用来更准确地计算实际工程中的非线性固结沉降。

The paper has put forward the amended Terzaghi theory by using coefficient of consolidation defined under non - linear condition and validated it using an example. The result indicated that using coefficient of consolidation defined under non - linear condition can make the result of Terzaghi theory better close to the result of practical settlement of clay. The amended Terzaghi theory can be better used in calculating the non - linear consolidation of clay.
