Highway route CAD aided design system

Abstract

The invention relates to a highway route CAD aided design system. The current specialized CAD software developing mechanism and group in China are weak; and compared with foreign excellent software, the traditional software level has later start and larger difference. In the middle and late 70s of 20th century, relevant highway scientific research units, institutions for higher learning and highway measuring and designing departments start to research and develop a road design calculation and optimization program and achieve an initial result; the developed program mainly substitutes a designer to carry out data processing and calculation due to the limitation of the current development environment (hardware and support software), and the program developed at the stage has single functionand narrower application range and is not a complete program system. The highway route CAD aided design system comprises comprehensive design of the plane, the longitudinal section and the cross section of a route, tabulation, drawing, digital ground model operation and database operation. The invention is applied to the field of construction of road bridges.

Description

Technical field: [0001] The invention relates to a method that closely combines terrain data collection, digital ground model and route CAD into an organic whole to form an integration covering the whole process of route design covering data collection and processing, route preliminary design, route construction drawing design and output design file 化系统. Background technique: [0002] From the road survey and design work, on the basis of obtaining various terrain raw data through various measurement technologies, the system can establish a strip-shaped digital ground model along the road, and then quickly and accurately provide the required road design All terrain data, that is, a large number of heavy survey tasks of road field survey work are completed in the house through the digital ground model operation, which truly realizes the integration of the road survey inside and outside the field based on computer-aided design. In this system, the user only needs to specify the hori...

Problems solved by technology

[0007] The current specialized road CAD software development institutions and teams in my country are very weak. Compared with foreign excellent software, the existing software level started relatively late, and the gap is still large.

In the middle and late 1970s, relevant highway research institutes, colleges and universities, and highway surveying and design departments began to develop and develop road design calculation and optimization programs, and achieved preliminary results. Due to the limitations of the development environment (hardware and supporting software) at that time, The program developed is mainly to replace the designer in data processing and calculation. The program developed at this stage has a single function and a narrow application area, and is not yet a complete program system.

However, these software lack support for digital ground models, and are only computer-aided design based on measured data
