| 摘 要： | 通过多年对粉煤灰振冲桩检测实践,应用多种检测方法,并进行比较,提出桩间土(粉煤灰)应以标贯、静力触探为主；认为复合地基载荷试验费用高,效果不佳,仅能验证是否达到设计标准,无法取得桩基承载力极限值.

| Abstract: | By years of practice with many testing methods and much comparison on vibroflotation piles in fly ash,this paper finds that the suitable testing methods for soil(or fly ash)between piles are SPT and CPT,and that the plate loading test for composite foundation is too expensive and not effective.It can only verify whether to reach the design standards,while it is hard to obtain the limiting value of bearing capacity of piles. |
