Geological Survey in Water Areas Based on Acoustic Strata Profile Technique

摘要

The disastrous geology survey in water areas for underwater pipeline construction has been finished with the acoustic strata profile technique. The strata profile has been obtained, which shows the bedrock is consecutive and no fault exists in the exploration area. The existence of at least two pipelines has been proved, and the depth of the previous pipelines is in the middle of sand layers. Therefore, the suggestion of pipeline construction at the depth of about 40m below the water level has been proposed to avoid the cobble layer and provide a covering layer to prevent pipelines from erosion by currents.
