静力触探法估算单桩竖向极限承载力在昆明某高层建筑中的应用

Estimating the Vertical Ultimate Bearing Capacity of Single Pile with Static Sounding Data in a High-rise Building in Kunming

《建筑桩基技术规范》(JGJ 94—2008)中,给出了用静力触探资料估算混凝土预制桩单桩竖向极限承载力标准值的计算公式。该规范出台几年来,在昆明地区工程实践中却应用不多,大多工程实践对单桩竖向极限承载力的估算仍以经验参数算法为主。通过实例,用静力触探资料对昆明某高层建筑进行了单桩竖向极限承裁力标准值的估算,并把估算结果和传统的经验参数法估算结果进行了对比,得出结论,以供参考。

The building pile technical specification （JGJ 94--2008 ） is provided the formula to estimate the vertical ultimate bearing capacity of single concrete precast pile with static sounding data. Although being issued for years, the specification was not used frequently in the engineering practices in Kunming, where the estimating of the vertical ultimate bearing capacity of single pile in most engineering practices are still according to experimental parameter. The vertical ultimate bearing capacity of single pile with static sounding data for a high-rise building in Kunming is estimated, and compared this result with the result which is estimated by the traditional algorithm based on experimental parameter, comes to a conclusion for reference.
