滁马高速清流河特大桥主桥深基坑施工,距离防洪大堤较近,大堤的附加不对称荷载对基坑产生偏载影响,会对基坑安全及围护结构受力产生影响.本文通过计算分析偏载对基坑安全及围护结构受力影响,进行合理的深基坑支护设计,采取有效的施工技术措施,动态的基坑变形观测,确保了主墩承台施工过程中基坑及防洪大堤的安全.
滁馬高速清流河特大橋主橋深基坑施工,距離防洪大隄較近,大隄的附加不對稱荷載對基坑產生偏載影響,會對基坑安全及圍護結構受力產生影響.本文通過計算分析偏載對基坑安全及圍護結構受力影響,進行閤理的深基坑支護設計,採取有效的施工技術措施,動態的基坑變形觀測,確保瞭主墩承檯施工過程中基坑及防洪大隄的安全.

Deep foundation pit construction of the Chuma-highway Qingliuhe main bridge,near the flood control embankment. Additional asymmetric load of the embankment Wil have an impact on the safety of foundation pit and retaining structure. In this paper, through analyzing the influence of partial load on the safety of foundation pit and retaining structure, reasonable design of deep foundation pit,take effective engineering measures,dynamic foundation pit deformation observation, ensure that the main pier construction process in the pit and flood control embankment safety.
