摘　　要：分析了苏北沿海地区(盐城、连云港)典型软土层中粉喷桩桩身质量的测试方法和结果。用标准贯入试验和现场取芯试验可以有效地检测粉喷桩桩身强度和主要影响因素;用低应变动测试验可以对粉喷桩实施普查,即对粉喷桩桩身的完整性做出合理的评价。提出将粉喷桩桩身强度与完整性测试结合起来,从而对粉喷桩桩身质量做出较全面的评价,为该地区粉喷桩复合地基的推广应用提供依据。This paper analyses the test method of qulity of powdered jet pile shaft in model soft foundation around seaside of north jiang- su and the test results.Pile shaft capacity and main factors are tested by standard penetration test and sit core test.By low train dynamic test pile are widely tested and the integrity of pries ahaft are evaluated.Combining pile capacity with integrity test,the paper evaluates thoroughly the qulity of pile shaft.Some suggestions are presented for the application of powdered jet pile composite foundation.
