摘要
针对悬臂开挖围护桩的受力特点,结合现场实测围护桩位移,提出了柔性桩的桩身挠曲方程及静力平衡原理反算桩后所受土压力,并以反算的土压力作为围护桩荷载,采用弹性地基法,计算出桩身位移,与郎肯主动土压力计算位移及实测位移进行对比分析,以验证其准确性。
In this paper, the mechanical characteristics of the cantilever excavation envelope pile, combined with field measurement the pile displacement, elastic pile inverse the pile soil suffered after pressure according to the pile deflection equation and the static balance principle, and to back calculation soil pressure as pile load elastic foundation calculated pile displacement, and the Lang are willing to take the initiative of earth pressure calculated displacement and measured displacement were compared to verify its accuracy.
