For the engineering projects, especially large projects, the construction time is long, complexity of construction geological conditions, sometimes appear quality defects. How to scientific and reasonable to take remedial measures for the quality defects of concealed work, or effective rectification, save time, cost, quality, safety aspects of the loss, become the important engineering problem. Drop anchor deep foundation pit wall because belongs to temporary works, do not belong to the main project, for the problems of verticality, can take measures to deal with deviations, in order to ensure the normal implementation of the project. According to the Suining two station engineering of deep foundation pit drop anchor wall verticality correction as an example, the national large-scale projects supporting the deviation, the role of a great reference. From the implementation of the index statistics, analysis shows that, to achieve even better than the specification requirements, and achieved the desired results.% 对于工程项目，尤其大型工程，由于工程建设时间长，建设地质条件的复杂性，有时难免出现质量缺陷。如何科学合理的对隐蔽工程质量缺陷采取补救措施，或者进行有效纠偏，挽回工期、成本、质量、安全方面的损失，成为工程重要难题。深基坑下拉锚式地连墙因为属于临时工程，不属于主体工程，对于垂直度方面存在问题，可以采取措施进行偏差处理，以保证工程正常实施。本文以睢宁二站工程中深基坑下拉锚式地连墙垂直度纠偏为例，对国家大型工程中的支护偏差处理，有很大的借鉴作用。从实施效果各项指标统计、分析表明，达到甚至优于规范要求，取得了预期成效。
