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 elastic thin cylinder.A unit thickness ring is considered as a plane-strain problem.With polar coordinate system the analytic solution is obtained.The calculated values agree well with the actual test values.
