大型深基坑支护牵涉面广，具体施工条件复杂，是一个综合性的岩土工程难题，目前还没有一套完整的理论依据及完善的施工规程。悬臂桩护坡是目前较常用的一种支护结构形式，郑州裕达国贸大厦的深基坑支护采用人工挖孔灌注桩作悬臂护坡桩，在护坡技术方面作了有益的探索，积累了一些经验教训，以供参考。
The support of large-scale deep foundation pits involves a wide range, and the specific construction conditions are complex. It is a comprehensive geotechnical engineering problem. At present, there is no complete theoretical basis and perfect construction regulations. The cantilever pile slope protection is a relatively common form of support structure. The deep foundation pit support of Zhengzhou Yuda International Trade Building adopts manual digging and perforating piles as cantilevered slope protection piles. It has made useful explorations in slope protection technology and accumulated some Lessons learned for reference.
