Application of High Density Resistivity Method in Seawall Detection

With the development and construction of the beach oil field, there are a large number of revetment projects in oilfield construction, such as beach seawall, etc. The marine environment of beach oil field is very complex and abominable. Seawall is not only affected by wind, wave and current, but also threatened by storm surge, sea ice and other natural disasters. After long-term service, there are different degrees of engineering quality and structural hidden trouble problems in seawall and other structures. Therefore, it is necessary to carry out the research on the detection technology of the hidden trouble problems of the seawall structure. The research can provide a scientific basis for the safe operation, maintenance and reinforcement of the seawall. Based on the application experience of high density resistivity method in engineering investigation, this paper studies the application of high density resistivity method in the detection of hidden dangers of seawall. This research starts with the selection of device types, and combines model analysis and field verification. The high density resistivity observation device and detection parameters suitable for structural detection of oilfield seawall engineering are determined. The research results provide technical support for the structural inspection of seawall engineering.
