摘要
针对表土段井筒作用有竖向负摩擦力的情况,本文介绍了沥青夹层复合井壁结构,分析了它的受力情况,给出了该井壁型式各部分主要尺寸的计算方法.
In view of negative frictional force on the shaft constructed in surface soil, this paper introduces the construction of the composite shaft lining filled with asphalt, analyses its mechanical characteristics, and then provides a method for the calculation size of its various parts.
