摘要
提出了特殊地层条件下有竖直附加力存在时的新型可缩钻井井壁结构形式，研究了槽型圈可缩装置的计算方法，通过模拟试验得到了相应的设计参数，并提出了新的井壁设计方法，为工程设计和应用提供了可靠依据。
The new type yieldable structure of drilling shaft lining to adapt the additional vertical force in thick alluvium is put forward.Calculating method of the yieldable installation is studied.Based on similarity tests,some design parameters are given.The new design method of shaft lining is discussed,which provides reliable basis for engineering application.
