摘要
本文介绍某特大型异形沉井采用轻型水力机械出土和新颖的降低地下水位的措施,使沉井顺利地穿越了深厚的粉细砂承压含水层,实现干下沉干封底的成功经验。
This article makes an introduction of a new method for sinking extra large and special shaped open caisson by the adoption of hydraulic excavation using portable devices and water-level-lowering measures. This method makes it possible to make a way through thick water-bearing hed of fine sand. realizing dry sinking and dry bottom-sealing.
