摘要
冻结法凿井技术在我国研究应用已历时65 a,成为我国立井井筒穿过深厚冲积层、深厚松软富水岩层主要的特殊施工方法,在立井深厚冲积层和深厚松软富水岩土层冻结壁设计理论与应用、高承载能力井壁结构设计与应用、冻结壁形成特性理论与应用技术、冻结段安全快速施工机制等诸多方面,取得了新的突破。我国在冻结法凿井理论与技术的研究和应用上,领先国际水平,形成了具有我国特点的深厚冲积层冻结法凿井理论和技术体系。
The freezing shaft sinking method has been applied in China for 65 years,and it has become the main construction method for vertical shafts to penetrate deep alluvial and soft water-rich rock strata.Many breakthroughs have been made,such as the shafts freezing wall design theory and application in deep alluvial and deep soft water-rich rock strata,the design and application of shaft lining structure with high bearing capacity,the theory and application technology of freezing wall formation characteristics,safe and fast construction mechanism in freezing section,and many other aspects.In the research and application of freezing shaft sinking theory and technology,our country leads the international level,which has formed an advanced theory and technical system of freezing shaft sinking in deep alluvium with chinese characteristics.
