摘　　要：以某深基坑工程土钉支护结构为例,采用现有设计规范对各层土钉的受力情况进行了分析,结果与实测值相差较大,采用考虑动态施工条件下的增量简化计算方法计算各层土钉内力,计算结果与实测值绘制的曲线分析比较吻合,得出增量法对动态施工条件下土钉内力计算简单可行,更符合工程实际。Taking the soil nailing structure of deep excavation engineering as an example, using the existing design specifications analysis the layers of soil nailing force. Compared with the measured values is large different. By considering dynamic construction under the condition of in cremental method of soil nailing internal force calculation, analysis of curve drawing calculation results with the measured values is consistent, the results show that incremental method for dynamic construction conditions affecting nail internal force calculation simple and feasible, is more in line with the engineering practice.
