中美印单桩承载力确定方法对比研究

Comparison and Study on Single Pile Bearing Capacity Determining Method in China,America and India

介绍了美标印标单桩竖向承载力公式法和中美印单桩静载试验法。结合实际工程地勘资料和试桩结果,阐述了单桩承载力的确定过程,并对三种规范确定的单桩承载力进行了比较。结果表明,美标印标单桩承载力公式法计算结果较为接近,试桩确定的单桩承载力国标与印标基本一致,而美标略小,美标印标试桩确定的单桩承载力均大于公式法计算结果。

The formula method of determing the single pile vertical bearing capacity in American and Indian code and static load testing method in Chinese,American and Indian code are introduced re-spectively.Based on geotechnical reports and pile test results of actual project,how to determine the single pile capacity is represented and the single pile bearing capacity determined according to three codes are compared.It's shown that the bearing capacity results calculated complying to American and Indian code formula method are close,the results determined by pile test method are almost the same for Chinese and Indian code,but slightly smaller for American code.Furthermore,for American and Indian code,the calculated results determined by pile test method are higher than that by formula method.
