软土地层小直径长距离泥水平衡盾构泥水处理选择及应用

Selection and Application of Slurry Treatment Technology of Small Diameter and Long Distance Slurry Balance Shield in Soft Soil Layer

为明确软土地层中小直径泥水平衡盾构泥水处理工艺选择的关键指标,从小直径长距离泥水平衡盾构特点与软土地层的地质特性出发,对泥水处理工艺选择的相关指标进行了分析。结合实际工程中应用的效果,对泥水指标控制方法和配套管理技术进行了完善。该技术对小直径长距离泥水平衡盾构泥水处理技术具有很好的指导意义。

In order to make clear the key indexes of slurry treatment process selection of small and medium diameter slurry balance shield in soft soil layer, the relevant indexes of slurry treatment process selection are analyzed based on the characteristics of small diameter and long distance slurry balance shield and the geological characteristics of soft soil layer. Combined with the effect of practical engineering application, the control method of slurry indexes and matched management technology are improved. This technology has a good guiding significance for the slurry treatment technology of small diameter and long distance slurry balance shield.
