Suitability assessment for construction of sealed caverns in granite mass of Jinzhou Economic and Technological Development Zone,Liaoning Province
摘要
Abstract
The granite mass in Jinzhou Economic and Technological Development Zone of Liaoning Province is evaluated for its potential to serve as a site for major engineering projects such as underground oil and gas storage.To support the site selection for sealed underground cavern construction in the area,this study first analyzed the geological characteristics of the rock mass and then employed methods including drilling,geophysical surveys,and laboratory tests to conduct individual assessments of rock mass permeability,mechanical properties,ground temperature,and rock quality.Based on these assessments,relevant indicators were selected,and the suitability for sealed cavern construction was comprehensively analyzed using the Analytic Hierarchy Process(AHP).The results indicate that the rock in the area is dense,hard,and relatively intact,with micro-to low-permeability.The groundwater table is shallow,and water reserves are poor.The groundwater,classified as sodium chloride and sodium bicarbonate types,poses only a weak corrosive risk to underground construction materials.At depths greater than 50 meters,the rock mass is predominantly of Class Ⅱ quality,characterized by high compressive strength,very low saturated water absorption,and moderate ground temperature,making it suitable for sealed cavern construction.Based on the evaluation,areas suitable for underground space development are primarily located in the northern and central parts of the area,which feature a superior geographical location,favorable natural conditions,convenient transportation,and limited surface structures.The findings of this study may provide a scientific basis for the site selection and construction of major underground projects in Jinzhou Economic and Technological Development Zone.关键词
