摘要
FIELD: construction of water-development works. SUBSTANCE: bore is drilled in investigated bedrock and former block is cast concrete uniaxially. Then filtration characteristics of rock mass under conditions of natural bedding, compression and tension are determined by feeding of water into bore under pressure. Simultaneously deformation characteristics of bedrock are defined. In this case characteristics of bedrock in zone of upper face of works is evaluated by data obtained under conditions of tension and in zone of lower face - by data obtained under conditions of compression. EFFECT: improved authenticity of determination of filtration characteristics. 2 dwg
