摘　　要：通过两个大型土钉支护深基坑工程的现场实测，测得了土钉应力分布、坡顶水平位移及土钉极限抗拔力，并用土工有限元程序ＰＬＡＸＩＳ进行计算，实测结果与有限元计算结果能较好地吻合。The paper presents the field measurement records of two large sites of soilnailing for excavation support, the stress distribution of soil nailing, lateral deflection at ground surface and limit pull-out resistance of soil nailing is measured Soil finite element program (PLAXIS) is used for calculation, the agreement between the measured and the calculated results is good
