Evaluation Of The Engineering Geological Environment And Control Measures In Tangshan City

Evaluation of urban engineering geological environment and disaster management 0is a multi-factors and multi-levels process. How to choose and use condition of engineering geological environment is very important in urban layout.Experiment is based on that fully collects and uses the predecessor marerial ,the entire Tangshan city is seleceted as the appraisal. Which were evaluated engineering geology question are taken into detailed research, with evaluation in science way. Which can proivide the basis for the research area geology environmental protection. The main research includes:Unifying through the open country investigation and study and the office work, useing this area of this area, the comprehensive thorough investigation, the analysis, and studies of engineering geology and the hydrogeological conditions, determineing the Tangshan urban each unit engineering geology environment quality appraisal target characteristic value.Establishes that the appraisal target system, the definite quality rank, and carries on the optimization to the quality model. Divides the environment engineering geology quality more land sector, is using the fuzzy synthesis judgment law to surplus to be possible to carry on the quality synthetic evaluation compared to the land sector.According to that environment engineering geology quality graduation result, Draws up that engineering geology environment quality district chart with the AutoCAD and GIS software.Which provides the direct-viewing reference for the decision-making body.The situation and development trends research geological disasters of Tangshan city by the map of that. According to special condition of geological environment on Tangshan city karst collapse and collapse of mined-out, the reasonable countermeasure of prevention are established.
