Three-dimensional Modeling and Stability Analysis of Slope of Landfill Site Based on Loosely Coupled Framework
In recent years,large-scale demolition and reconstruction of old houses and road construction have led to a sharp increase in abandoned soil volume,landfill sites have become important ancillary projects in urban construction.Due to the loose structure and poor compaction of the slope structure of the landfill sites,it is more prone to deformation and damage than natural slopes,and the safety management of the landfill sites has received much attention.In order to achieve rapid analysis of the stability of landfill sites under complex working conditions,a technical framework combining visualization modeling and simulation calculation was constructed by building a loose coupling system of ArcGIS and GeoStudio.To improve the visualization effect of the model,the accuracy of the formation surface was improved by using virtual drilling and spatial interpolation methods,and the three-dimensional modeling technology of the landfill sites was improved.Python language was used as the program interface to complete cross-platform model data exchange,achieving rapid prediction of the stability of landfill site slopes under all-time and space working conditions.The application example of the Bai Zhang Chi Pu building landfill site in Minqing County shows that this solution can achieve high-quality identification of any section of the landfill sites and rapid prediction of the stability change law under complex working conditions.It can be concluded that the loose coupling method has significant applicability and practical value in the stability analysis.
