应用SPB—1塑料排水板处理软基

在软土和超软土地基中，为了加速土壤的排水固结，通常采用排水砂井作为垂直排水通道，塑料排水板处理软基，其工作原理，布置方法，设计方法与排水砂井相似，１９８８年珠江电厂厂区软基加固工程是采用塑料排水板加固地基，经试验，其力学性能满足工作需要，排水的效果良好，施工速度快，降低了地基加固费用。

Application of SPB-1 Plastic Draining Plate in the Treatment of Soft Foundation

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 as goodeffect in drainage, fast speed in construction and low cost in the reinforcement of foundation.
