摘　　要：现行载荷试验稳定标准基本是五、六十年代标准的延续 ,但随着压板面积的增大 ,上述标准已显太严 ,使试验观测时间过于漫长。本文结合工程实际 ,通过各方论证 ,建议将碎石桩复合地基载荷试验稳定标准改为≤ 0 2 5mm ,从而缩短观测时间 4 7% 。The stability standard of bearing test in force is almost one of fifities and sixties.The observing time of the test is too long due to loading plate becoming bigger.Combined with several projects practice and argumenton defferent sides in this paper.Writer suggest changing the stability standard of bearing test of composite subgrade of vibro replacement stone column for being≤0 25mm,thus shorten observing time 47 percent and raise efficiency of test.
