双桥静力触探法在估算预应力混凝土管桩单桩承载力中的应用

摘要

With the application of prestressed concrete piles along Huaihe River in Bengbu ,accurate calculation of the standard value of ultimate bearing capacity of single pile has important engineering significance .Based on practical projects ,prestressed concrete piles vertical ultimate bearing capacity values are estimated by double bridge cone penetra -tion test data ,and the estimated results are compared and analyzed with traditional experiential parameter methods .%随着预应力混凝土管桩不断的应用，准确计算单桩竖向极限承载力标准值有着重要的工程意义。本文结合蚌埠沿淮地区某工程实例，利用双桥静力触探资料估算预应力混凝土管桩单桩竖向极限承载力标准值，并把其估算结果和传统的经验参数法估算结果进行了对比与分析，得出结论，以资借鉴。
