Research on Adaptive Modeling Technology for Sound Barriers in Land Transportation Engineering
摘要
Abstract
To address the challenges such as low efficiency of traditional 2D design,insufficient 3D visualization,and inadequate result delivery methods of sound barriers in land transportation engineering,a sound barrier modeling and design module for a comprehensive route selection system was developed using B/S architecture based on GIS+BIM technology.The system accessed geographic and geological basic data services,loaded massive heterogeneous data onto the Digital Earth,and created geographic and geological scenes.Based on modeling parameters and terrain and geological conditions,the system achieved rapid modeling of major structures in land transportation engineering,including subgrades,bridges,tunnels,stations and ancillary facilities.Based on the general diagrams of sound barriers in land transportation engineering,a universal model library for sound barriers was established.The principles for setting sound barriers were summarized.Standard vector data for residential buildings were produced through GIS software processing or remote sensing interpretation.Based on the system's coordinate transformation and projection calculation capabilities,an adaptive layout algorithm for sound barriers was summarized and refined.The system implemented adaptive modeling of sound barriers according to the principles of sound barrier setting,with the ability to update and modify,and also completed sound barrier project quantity statistics.The system enabled the adaptive modeling of sound barriers for a 100 km land transportation project in just 1 to 3 minutes,significantly improving the efficiency of sound barrier design in land transportation engineering.It also expanded 3D visualization and result delivery methods for sound barriers,providing data support for scheme comparison and project decision-making.The research results enriched the 3D data assets and applications of sound barriers in land transportation projects and improved the integrated operation system for the entire lifecycle of land transportation engineering,including surveying,design,construction,operation and maintenance,and promoted the development of environmental protection in land transportation engineering towards informatization,digitization,and intelligence.关键词
