Establishing method for plateau long-distance large engineering surveying control system

Abstract

The invention discloses an establishing method for a plateau long-distance large engineering surveying control system. The establishing method comprises the steps that firstly, a large trunk canal control net is established to unify engineering surveying frameworks; then, a plurality of building control nets are established to meet the precision requirements of construction of corresponding buildings; finally, the trunk canal control net and the building control nets are effectively linked, and integral construction surveying control is formed. The method is oriented to plateau long-distance large engineering construction, a high-precision surveying and mapping guarantee is provided, the integral design and unified deployment of engineering are achieved, and the precise engineering surveying control system is established; design, construction, construction management and supervision maintenance along the line of engineering are carried out under the framework with unified precision and standards.

Description

technical field [0001] The invention relates to the technical field of engineering survey, more specifically, it relates to a method for establishing a plateau long-distance large-scale engineering survey control system. Background technique [0002] The establishment of engineering measurement control system is the foundation and basis of engineering construction. The accuracy of the control system directly affects the accuracy of measurement and release of engineering trunk lines and buildings. Therefore, in the project planning stage, it is necessary to design the corresponding measurement control system according to the measurement and release requirements of the project and the characteristics of the project to ensure the accuracy requirements of the project. For complex large-scale engineering projects, it is necessary to have first-class surveying and mapping guarantee to realize the overall design and unified deployment of the project, and establish an accurate engin...

Problems solved by technology

[0005] The purpose of the present invention is in order to overcome the deficiency of above-mentioned background technology, and provide the establishment method of plateau long-distance large-scale project survey control system, solve the plateau long-distance large-scale project, because the length reduction value is relatively large, will produce actual amount edge The difference between the length and the back-calculated theoretical side length is too large, resulting in the problem that the measurement accuracy of engineering trunk lines and buildings exceeds the limit
