In order to quicken the drainage and consolidation of soil, sand drains are usually used as vertical emissaries in soft or supersoft foundation. The working principle, arrangement and design of the treatment of soft foundation by plastic draining plates aresimilar to those of sand drain. Plastic draining plates were applied to the soft foundation treatment project for the Zhujiang Power Station in 1988. According to the tests, the mechanical behavours satisfied the working requirements with such advantages ...
