| 摘 要： | 以驻屿店市政府搬迁区某小区的一栋民用住宅楼基础沉管灌注桩试桩的静载试验数据结果为依托，通过现场静载试验数据结果来确定单桩极限承载力标准值以及承载力特征值，对比当前《建筑桩基技术规范》（JGJ94—2008）的计算值，提出了适合于驻马店地区沉管灌注桩设计的经验公式。该方法在保障安全、经济、适用的基础上可节约大量材料，同时也可为其他地区桩摹设计提供合理的参考经验依据。

| Abstract: | Relying on the data of static load test on test pile in the foundation of a residensial building of Zhumadian and by the field data of static load test, the standard value of ultimate bearing capacity of single pile and the characteristic value of bearing capacity were determined. Comparing to the calculated value in Technical Code for Building Pile Foundations （JGJ 94 -2008）, empirical formula proper to the driven grouting pile design in Zhumadian area was put forward, which could ensure safe and economic construction with production materials saving, and could be the reference to other pile foundation design. |
