摘要： 从增加排水通道、让固结水尽快排出的角度出发，探讨了两种工程措施的固结排水效果。两种措施其一为综合采用塑料排水板、粗砂垫层与土工格栅，其二为塑料排水板结合竖向排水引管。观测结果表明，施工期固结沉降为60~80 cm。采用竖向排水引管等固结排水方式为固结排水加固措施提供了较好的思路及想象空间。

Abstract: Two consolidation drainage measures were discussed from the viewpoints of increasing drainage channel and discharging consolidated water as soon as possible. The one was the combination of plastic drainage plate, sand cushion and geogrid, the other was the combination of plastic drainage plate and vertical drainage pipe. Monitoring results showed that the consolidation settlement was 60~80 cm during construction. It was the new technology of the vertical drainage pipe in the consolidation drainage measures.
