Abstract
In-situ measurements of tunnels deformation for Saint-Petersburg subway are given. Time dependable wave character of tunnels deformation in the form of rising and lowering was discovered. It was established that periodical rising and lowering of tunnels occur along the track section with disrupted rock mass and tectonic fissure. It was suggested that tunnel stability prediction technique is based on rate of it displacement.
