钢板桩围堰广泛应用于江河湖海等水中承台的施工。因现场水文地质条件复杂、环境多变,对钢板桩围堰及其内支撑的安全性影响较大。鉴于此,针对海河特大桥R39号墩钢板桩围堰,在理论分析的基础上,进行各工况下围堰内支撑的受力情况与现场实测结果比较分析,两者基本一致,取得良好的效果。
Steel sheet pile cofferdam is widely used in the construction of rivers and lakes and other water cap. Due to the complex hydrogeological conditions on the site and the changing environment, the safety of steel sheet cofferdam and its internal support is greatly affected. In view of this, aiming at the steel sheet pile cofferdam of R39 pier of Haihe Grand Bridge, on the basis of theoretical analysis, the force condition of the cofferdam under each working condition is compared with the field measured results, the two are basically the same, and a good effect.
