摘　　要：通过典型工程,针对该砂层内各亚层工程地质特性差异进行分析和细化分层,参照DGJ32/TJ208—2016《岩土工程勘察规范》进行桩基参数取值,提出以该层中的密实砂层亚层作为预制桩桩端持力层的建议,并结合单桩竖向抗压静载试验结果进行桩基参数验证,为泗阳城区浅层砂层的进一步研究提供了基础资料,也为该地区15~18层高层预制桩桩端持力层选择提供了一定的参考和借鉴。Combined with a typical engineering case,differences of engineering geological characteristic between each sub layer in the sand layer are analyzed and the stratification is refined.Based on the pile foundation parameters selected according to DGT32/TJ208—2016 The Geotechnical Engineering Investigation Code of Jiangsu Province,the suggestion of using dense sand sublayer as as prefabricated pile bearing stratum is proposed.Rationality of pile foundation parameters is proved by single pile vertical compressive static load test.It provides basic data for further study of shallow sand layer in Siyang city,at the same time,it also provides a certain reference for the selection of precast pile end bearing layer of 15~18 storey high-rise residential buildings.
