RETRACTED ARTICLE: Excavation and support method of tunnel with high ground stress and weak surrounding rock based on GIS

Abstract

In the process of road development and road construction, there will be some problems. In some places with poor terrain, it is not only difficult to construct, but also blocked by mountains. In order to get through the roads, tunnels must be dug from the mountains. Tunnel construction is very complex and dangerous; if there is no strong technical support, it is easy to cause the construction personnel to be injured, and the setting will lead to problems in road engineering. In the process of construction, the most difficult problem is the collapse or deformation of the top of the tunnel. In order to solve the similar problems, it is necessary to design an effective support method to control the rock deformation in the tunnel. Although the design and attempt of support means are constantly advancing, researchers have not given a unified standard on this issue. On the basis of collecting a large number of data, this paper makes a practical investigation on the tunnel construction, analyzes various parameters in the construction process by using a variety of data analysis and integration methods, and finally links the contents of the project decomposition structure with the GIS model to provide more theoretical support for the tunnel construction.
