摘要

通用分段的设计和分段组装的偏差控制对于稳健和低风险的隧道施工至关重要。我们提出了一个基于建筑信息模型(BIM)的框架,用于通用分段的参数化建模、自动装配和偏差控制。首先,基于 BIM 可视化编程语言(VPL),针对不同的项目生命周期建立了不同详细程度(LoDs)的分段模型。然后,对参数化分段组装的几何约束、要求和程序进行提炼,开发出一种结合了新型排版算法和三维路径重新规划算法的程序。排版是通过引入点指示矩阵、按边描述分段特征以及在 VPL 中操作几何图形来实现的。同时,以非均匀有理 B-样条曲线(NURBS)和弧线为基本形状的三维路径重新规划用于解决排版后不可接受的偏差情况。最后,在一条引水线路上对所提出的框架进行了验证,发现它比以前的方法更有效、更准确。

BIM-based framework of automatic tunnel segment assembly and deviation control

The design of universal segments and deviation control of segment assembly are essential for robust and low-risk tunnel construction. A building information modeling (BIM)-based framework was proposed for parametric modeling, automatic assembly, and deviation control of universal segments. First, segment models of different levels of detail (LoDs) were built based on BIM visual programming language (VPL) for different project life cycles. Then, the geometric constraints, requirements, and procedures for parametric segment assembly were distilled to develop a program that combines a novel typesetting algorithm with a 3D path replanning algorithm. Typesetting is implemented by introducing a point indication matrix, characterizing segments by sides, and manipulating geometries in a VPL. Simultaneously, 3D path replanning, with non-uniform rational B-splines (NURBS) and arcs as basic shapes, was used to resolve unacceptable deviation situations after typesetting. Finally, the proposed framework was validated on a water diversion line and was found to be more effective and accurate than the previous method.

期刊介绍: Underground Space is an open access international journal without article processing charges (APC) committed to serving as a scientific forum for researchers and practitioners in the field of underground engineering. The journal welcomes manuscripts that deal with original theories, methods, technologies, and important applications throughout the life-cycle of underground projects, including planning, design, operation and maintenance, disaster prevention, and demolition. The journal is particularly interested in manuscripts related to the latest development of smart underground engineering from the perspectives of resilience, resources saving, environmental friendliness, humanity, and artificial intelligence. The manuscripts are expected to have significant innovation and potential impact in the field of underground engineering, and should have clear association with or application in underground projects.
