Based on the fast-track project in Zhengzhou,by processing software for deep excavation neighbors viaduct bridge piles deep cutting slope conduct reinforcement design of anchored piles,the site monitoring data were analyzed. The results showed that the use of anchored piles to ensure safety requirements during deep cutting excavation and being used,and it is economic and with high construction speed .%以郑州某快速通道改建工程为例，通过理正深基坑软件对近邻高架桥桥桩深路堑边坡进行桩锚支护加固设计，并结合现场监测数据进行分析。工程实践说明：采用桩锚支护能够保证深路堑在开挖和使用期间的安全性要求，而且具有经济，施工速度快等优点。
