CORROSION-WEATHERED RED LAYER CHARACTERISTICS AND TREATMENT STUDY OF SUBWAY STATION EXCAVATION
Corrosion-weathered red bedrock is a special weak strata that is formed in the weathered or strongly weathered red bedrock under specific circumstances,the characteristics of which are analyzed from the site conditions,spatial distribution,mineral composition,physical and mechanical indexes in this paper.The influence of corrosion and weathered red bedrock existing TIYUGONGYUAN subway station foundation during excavation was analysed,and reasonable treatment measures were proposed.Reasonable depth was compared by numerical simulation,calculations result shows that:ahead of the surface jet-grouting reinforced can meet the requirements of foundation stability,and the reasonable depth is 3m under station foundation,which can provide a reference to similar projects in corrosion and weathered red bedrock.
