| 摘 要： | 通过工程实例,对目前深井冻结工程中的水文孔不溢水原因进行了较详细的分析,提出了应该从水文孔报道层位的设计、水文孔的结构、冻结管的偏斜控制、钻孔的施工质量控制、地下水流速度控制和根据不同工程和地质条件对水文孔溢水时间的预测以及加强冻结信息化监测和分析等方面采取措施,来保证水文孔的正常溢水和冻结井筒按时开挖。

| Abstract: | The reason of noneoverflow from hydrological hole in deep shaft sinking with freezing technology was discussed in detail.In order to guarantee required overflow from hydrological hole and shaft excavation on schedule,some measurements were brought up,including proper design of hydrological hole location in stratum,proper determination of hydrological hole structure,control of bore hole deflection,control of bore hole performance quality,control of groundwater flow velocity,prediction of overflow time from hydrological hole in different engineering and geological conditions,intensive monitoring and analysis of information in deep shaft sinking with freezing technology. |
