Abstract: Siphon drainage combined with surcharge loading is a new technology for soft ground improvement,in which the clogging issue of soil column in siphon flow is critical. The results show that the clay column is prone to form a blockage in the curved section of the siphon tube. Siphon tubes with inner diameter of 4 mm are widely used in field engineering. When the radius of the curved section is greater than 40 cm and the height of the clay column is greater than 4 cm, the clay column will clog in the siphon tube. Aiming at the clogging problem,the critical height solution of clay column under siphon flow is derived by using the particle subsidence model and corresponding hydrodynamic theory. According to the above solution, the anti-clogging measures are proposed to guarantee the siphon drainage operate smoothly. In practice, the siphon drainage process can be maintained by reducing the radius of curved sections, the length of siphon tubes, and the height of siphon outlets.

Key words: siphon, motion characteristic, clay column, clogging
