摘要
结合南昌地区自平衡试桩法的一个工程实例,将自平衡试桩法测试结果转化为传统静载法的荷载—位移曲线,验证了按荷载相等的原则进行转换是偏于安全的。使用3种基本函数曲线模型与生长曲线模型分别预测极限承载力,根据拟合精度,得到指数曲线模型与生长曲线模型的适用性较好,对南昌地区的折减系数的取值方法提出了合理建议,所做研究工作对于自平衡试桩法在南昌地区的实践与推广,具有重要的促进意义和借鉴价值。
Combining with an engineering example of self-balanced test results in Nanchang,it＇s introduced the conversion from the self-balanced test results to the traditional static loading method of the load-displacement curve,and it is proved that the conversion is safer according to the principle of equal load. It is predicted the ultimate bearing capacity of piles according to the three basic function curve models and the growth curve model,and obtained that exponential curve model and growth curve model have better applicability according to fitting precision,and the reduction factor in Nanchang area is suggested. The research work is of great significance and reference value for the practice and popularization of self-balanced test pile method in Nanchang area.
