Abstract

The invention discloses a towed underwater geological electrical method detection system and a method. The system includes: an underwater electrical cable, simple underwater electrodes, water pressuremeasurement and sensing units, an electrical cable floating and sinking unit, an underwater GPS positioning system, an inflator, an electrical method data collection and storage module and a data processing module. The underwater electrical cable is fixed with the electrical cable floating and sinking unit. The electrical cable floating and sinking unit is connected with the inflator. The underwater electrical cable is connected with the electrical method data collection and storage module and the data processing module in turn. The simple underwater electrodes and the water pressure measurement and sensing units are fixed on the underwater electrical cable. The underwater GPS positioning system includes responders, a shipboard transducer and a GPS. The responders are fixed at simple underwater electrodes of a front part, a middle part and a tail part on the underwater electrical cable. The responders are connected with the shipboard transducer in a wireless manner. The GPS is fixed on a tugboat. The towed underwater geoelectrical detection method and the method provided by the invention systematically solve the deficiencies and the problems still existing in current underwater geological electrical method detection, and have good application prospects.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, and more specifically relates to a towed underwater geological electrical detection system and method. Background technique [0002] With the acceleration of the urbanization process in our country, the infrastructure construction in various regions is in full swing. Among them, underwater infrastructure construction related to underwater rock and soil structure, underwater environmental resources, and underwater engineering construction projects for crossing rivers and rivers has increased year by year. Therefore, it is of great significance to analyze and judge geological information such as underwater geological structure and other geological information in advance through relevant technical detection means, which is of great significance for later engineering design, measure formulation, and safe construction. [0003] At present, the technical means to obtain the underwater ...
