Design method of fore shaft steel pipe pile-cast-in-situ bored pile supporting composite cofferdam system
The invention discloses a design method of a fore shaft steel pipe pile-cast-in-situ bored pile supporting composite cofferdam system. The design method comprises the steps that firstly, preliminary design of a fore shaft steel pipe pile cofferdam system and a soil retaining supporting cast-in-situ bored pile system is completed; 2, a stress analysis three-dimensional model of the composite cofferdam system is established, specifically, the stress conditions of the fore shaft steel pipe pile cofferdam system and the soil retaining support cast-in-situ bored pile system are analyzed, and a cofferdam stress analysis three-dimensional model and a support pile stress analysis three-dimensional model are correspondingly constructed; and step 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 soil retaining support cast-in-situ bored pile 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.
本发明公开了一种锁口钢管桩‑钻孔灌注桩支护复合围堰体系的设计方法，包括：步骤一、完成锁口钢管桩围堰体系、挡土支护钻孔灌注桩体系的初步设计；步骤二、建立复合围堰体系的受力分析三维模型：分别对锁口钢管桩围堰体系、挡土支护钻孔灌注桩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挡土支护钻孔灌注桩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。
