摘　　要：解答了顶面不排水、底面排水边界条件下的太沙基一维固结微分方程,并比较分析了不同坐标系统下、不同边界条件下的单面排水太沙基一维固结微分方程的解答。发现由于太沙基一维固结理论是建立在荷载作用面为无限大的假定之上,且不考虑土体与水的质量,因此顶面不排水、底面排水解与顶面排水、底面不排水解在两种坐标系统下具有等价关系。The one-dimension Terzaghi consolidation differential equation with boundary conditions,in which the top is drainable and the bottom is undrainable was solved,and the solutions obtained from several different references were analyzed.It was found that the differential equation solutions were equivalent with different reference frames,for the one-dimension Terzaghi consolidation theory is founded on the assumptions that load acting surface is infinite and the mass of soil and water is ignored.
