基于规划核实的地下建构筑物三维建模方法

Build Three- dimensional Modeling of Underground Structure Based on Planning Verification

地上下一体化三维建模是智慧规划和管理决策的基础。在地上、地表三维模型的基础上,如何实现快速、高精度、低成本、高效率的地下空间三维建模,实现地上下的三维一体化成为研究的重点和难点。本文在分析地下空间规划核实的基础上,提出了基于规划核实的参数化地下建构筑物的三维建模方法,并以常州为实例,通过地下空间三维可视化系统的推广与应用,验证了该方法的实用性和有效性。

Integratedsurface and subsurface three- dimensional modeling is the foundation of wisdom planning and management decisions. How to achieve fast,high- precision,low- cost,high- efficiency three- dimensional modeling of underground space basis on the three- dimensional surface model to achieve the three- dimensional integrated is the key and difficult research. This article proposed parametric verification of underground structures 3D modeling methods based on the verification of underground space planning,and in Changzhou for instance,through the promotion and application of underground space visualization system to verify the utility of this method and effectiveness.
