一、前言过去,对饱和软粘土地基的研究工作,着重于解决地基的强度及稳定问题。所以,在强度特性及其测定方法方面进行了大量的工作,尽管还存在不少问题,但总算有一套比较成熟的理论及相应的测试技术。至于软粘土的变形问题,由于缺少可行的计算方法,在这方面的研究工作还是比较薄弱的。随着电子计算技术及有限单元法的发展,有可能对边界条件、受荷情况及施工程序 I. Preface In the past, research on saturated soft clay foundations focused on solving the problem of strength and stability of foundations. Therefore, a great deal of work has been done on the strength characteristics and its measurement methods. Although there are still many problems, there is a set of more mature theories and corresponding testing techniques. As for the problem of deformation of soft clay, due to the lack of feasible calculation methods, the research work in this area is still relatively weak. With the development of electronic computing technology and finite element method, it is possible to perform boundary conditions, loading conditions, and construction procedures.
