The Application of Elastic Wave Measurement to the Deep Holes in the Bedrock of a Nuclear Power Station

In this paper we present the principle and technique for measuring velocity of elastic waves in the bedrock with deep holes, and the effective watertight and pressure-proof measures taken. Using this method, the measurement in the bedrock of the reactor of a nuclear power station with holes (120m in depth) are completed with the anticipated results. The data, processed and analysed, have been provided for the construction of the above-mentioned nuclear power station.
