摘要: 基于理论与实测分析,提出了用逐次线性概似法加上残差修正,利用数量较少的沉降观测数据来预测PHC桩(超高强预应力管桩)的竖向极限承载力.所附的大量工程实例的分析表明,这个方法精度较高,可操作性较强.

Abstract: Based on theoretical analysis and actual measurement, a gradual linear approximation method with residual error correction is proposed to predict the vertical ultimate bearing capacity of PHC piles (pre-stressed pipe pile with super high strength) using less dada of settlement observation. A series of practical examples show that this method has comparatively high precision and serviceability.
