Abstract
Due to the complicated geological condition with fractured rock mass,the virgin condition of the site of Gomal Zam Dam in Pakistan cannot meet the foundation condition required for constructing a concrete dam.Based on the in situ investigation and experiment,the treatment scheme of large range and depth consolidation grouting is then adopted.Combined with grouting experiment,the effect iveness of the consolidation grouting on enhancing the deformation modulus is verified,while a finite element analysis is made on the dam body with the rock physical and mechanic parameters after the treatment of consolidation grouting as well.On the basis of the demonstrations made in several aspects,the concrete gravity arch dam with the height of 133m is successfully built up under the condition of intensively fractured rock mass through an elaborative design concerned.The study result can provide references for design of the concrete gravity arch dams.关键词
