粉喷桩承载力的确定及影响因素分析

Analysis of the bearing capacity determination and its influencing factors on powder jet piles

利用邯郸市某工程粉喷桩的单桩载荷试验成果 ,探讨了土层有机质含量、桩身强度和桩身龄期对单桩承载力的影响 ,分析并论述了在采用单桩载荷试验确定单桩承载力时 ,应根据不同的影响因素 ,分别采取桩身强度法、相对沉降法和极限荷载法等不同的方法和标准 ,以上三种方法和标准的正确选用 。

The problems of the single pile strength influenced by the organic contents, strength of pile bodies and the age are discussed through the results of the loading tests in Handan. According to the different influence factors, the method of the pile bodies strength, relative settlement and the ultimate load of piles should be individually adopted while using the load tests to determine the capacity of the piles. Which is very significant to the design and test in the real projects.
