地下圆形连续墙支护结构的水平位移公式

THE HORIZONTAL DISPLACEMENT OF UNDERGROUND CIRCULAR CONTINUOUS WALL STRUCTURE

摘要: 以圆形地下连续墙支护结构为研究对象，将地连墙结构简化为弹性薄壁圆筒，在圆筒上截取单位厚度圆环作为研究对象，将空间问题转化为平面应变问题，利用弹性力学建立极坐标方程，求得圆形地连墙支护结构的水平位移公式. 最后，将推导公式应用于具体工程实例，计算值与实测值能较好的吻合.

Abstract: The circular underground continuous wall is studied in the paper. The continuous wall is simplified as an elasticthin cylinder. A unit thickness ring is considered as a plane-strainproblem. With polar coordinate systemthe analytic solution is obtained. The calculated values agree well with the actual test values.
