摘　　要：阐述了特殊地层条件下井壁受力的新观念及设计井壁的荷载组合；通过模拟试验提出了能适应竖直附加力的新型冻结井壁结构和钻井井壁结构，并给出了设计参数和设计方法；开发出从改变井壁结构方面防止新建井筒井壁破裂的技术．A new concept of stressed state as well as the design of loads on shaft lining under special stratum conditions is expounded. A new type of freezing and boring shaft lining structure capable of adapting a vertical additional force is put forward after modelling tests, and some parameters and methods for the design are given. A new technique for proventing a newly constructed shaft from fracturing is developed by changing the structure of shaft lining.

关 键 词：模拟试验 井壁结构 井壁 破裂机理 地层条件
