摘要
采用积分变换、算子法研究了多层地基二维Ｂｉｏｔ固结问题，获得地基表面作用荷载时任意层内任意点应力（包括孔压）、位移（包括流体流量）的一般积分形式解。按照本文的方法也能获得多层地基Ｂｉｏｔ固结的“Ｍｉｎｄｌｉｎ问题”的解答。本文的结论可推广应用于边界元法求解多层二维Ｂｉｏｔ固结问题。
Based on Biots theory , the two dimensional consolidation problems of layered soils are studied by means of integral transform method and the arithmetic method. The general integral solutions of stress (including pore pressure) and displacement (including fluid flow) in any layer are derived with the loading acting on the surface of soils. According to the methods proposed in this paper, the consolidation solution of “Mindlin” problem in layered soils can also be achieved. The results obtained in the paper can be utilized to solve the two dimensional consolidation of layered soils by boundary method.
