1.问题的概况和评述众所周知,在不均质无粘性土中水的渗透,当水动力条件和地质条件特别恶劣时,土的细颗粒可能流失。细颗粒由土层中流失和在孔隙中移动的过程称为管涌。估计土中出现管涌的可能性是水工建筑和工业建筑设计的重要、复杂和困难的问题。要是这一问题不加以解决就不能保证工程建筑物的安全。
1. Overview and review of the problem It is well-known that in the infiltration of water in an inhomogeneous cohesive soil, when the hydrodynamic conditions and geological conditions are particularly poor, fine particles of the soil may be lost. The process of the loss of fine particles from the earth and the movement in the pores is called piping. It is estimated that the possibility of piping in the soil is an important, complicated and difficult problem in the design of hydraulic and industrial buildings. If this problem is not resolved, the safety of the engineering building cannot be guaranteed.
