耦合三维地层模型的复杂高桩结构桩基设计

针对复杂高桩结构桩基设计的空间问题和传统地质资料的表达不足,为信息化、可视化管理桩基,提出了建立桩基信息数据库;基于工程区域的多源地形、地质数据,引入三维地层建模技术,建立了复杂高桩结构的三维地层耦合模型,并实现桩基和地层的三维重建、碰桩检测、桩位优化、持力层的选取、桩长及轴向承载力计算、桩位自动绘制等可视化辅助设计功能,极大提高了复杂高桩结构桩基设计的效率与水平。

Pile foundation design of complex pile-supported structure integrated with 3D strata model

To counter the spatial issues of pile foundation design for complex pile-supported structure and lack expression of traditional geological data, we establish the pile information database for digitally and visually managing piles to facilitate design work. By coupling 3D piles model and strata-graphic model, we achieve several visual-aided design functions, such as reconstruction of piles and strata, collision detection and optimization of piles layout, selection of pile bearing stratum, calculation of pile length and axial bearing capacity, and automatic output of piles layout in 2D. The successful application of the technical solutions has improved the efficiency and level of pile foundation design for complex pile-supported structure.
