自Gibson等在1967年提出了以孔隙比为自变量的一维大变形固结理论以来,不少学者通过数值法进行求解。本文在Gibson固结理论的基础上,推导出以超静孔压为基本未知量的一维大变形固结方程,并采用分离变量法,以傅立叶级数形式给出了方程的近似函数解表达式。 Since Gibson et al. proposed the one-dimensional large deformation consolidation theory with the void ratio as an independent variable in 1967, many scholars have solved it by numerical methods. Based on the Gibson consolidation theory, this paper deduces the one-dimensional large deformation consolidation equation with the excess pore pressure as the basic unknown quantity, and adopts the separation variable method to give the approximate function expression expression of the equation in the form of Fourier series. formula.
