Deepwater composite cofferdam system suitable for complex embankment area of tidal river channel and design method thereof
The invention discloses a deepwater composite cofferdam system suitable for a tidal river complex embankment area and a design method of the deepwater composite cofferdam system. The design method comprises the steps that firstly, primary design of a Larsen steel sheet pile cofferdam system and a cast-in-situ bored pile supporting system is completed; 2, a stress analysis three-dimensional model of the composite cofferdam system is established, specifically, the stress conditions of the Larsen steel sheet pile cofferdam system and the cast-in-situ bored pile supporting system are analyzed, so that a cofferdam stress analysis three-dimensional model and a supporting pile stress analysis three-dimensional model are correspondingly established; 3, analyzing deformation of the soil retaining support cast-in-situ bored pile: analyzing the deformation condition of the soil retaining support cast-in-situ bored pile based on the support pile stress analysis three-dimensional model, and determining whether overall stability checking calculation and structural checking calculation of a cast-in-situ bored pile support system need to be carried out or not; therefore, the interlocking steel pipe pile-cast-in-situ bored pile supporting composite cofferdam system meeting the requirements is obtained, and the construction safety is met.
本发明公开了一种适于潮汐河道复杂堤岸区域的深水复合围堰体系及其设计方法，包括：步骤一、完成拉森钢板桩围堰体系、钻孔灌注桩支护体系的初步设计；步骤二、建立复合围堰体系的受力分析三维模型：分别对拉森钢板桩围堰体系、钻孔灌注桩支护体系的受力情况进行分析，以对应地构建出围堰受力分析三维模型、支护桩受力分析三维模型；步骤三、分析挡土支护钻孔灌注桩的变形：基于支护桩受力分析三维模型分析挡土支护钻孔灌注桩的变形情况，并确定是否需要进行钻孔灌注桩支护体系的整体稳定性验算、结构性验算，从而获得符合要求的锁口钢管桩‑钻孔灌注桩支护复合围堰体系，满足施工安全性。
