Description

Dead weight type multi-parameter ocean shallow surface geological monitoring system and data interpretation method Technical Field The invention belongs to the technical field of ocean monitoring, and particularly relates to a dead-weight multi-parameter ocean shallow surface geological monitoring system and a data interpretation method. Background Along with the development and application of ocean resources in China, the period of developing operation on the seabed is more and more, but the understanding of the geological condition of the ocean bottom is still in the primary stage, and ocean geological data are required to be acquired through various means. The method is particularly important for acquiring data of geological environment of the submarine sediment, the type occupies most of the area of the seabed, and various engineering operations such as modern wind power, mineral products, buildings, cultivation and the like are required to be carried out on the submarine sediment, so that the method is particularly important for acquiring geological data information of the ocean shallow surface layer. Currently, in the prior art for collecting geological data of a shallow ocean surface, an operation mode of penetrating a probe rod into a submarine sediment and integrating a plurality of sensors on the probe rod is generally adopted. The probe rod type monitoring equipment is implanted to a certain depth below the seabed in a mechanical mode, and the integrated sensor can perform in-situ measurement on local parameters such as pore water pressure, temperature, gradient and the like of surrounding soil, so that fixed-point and contact type data collection is realized. However, the prior art solutions have significant limitations. First, the deployment and operation of the system are highly dependent on large-scale special drilling equipment or heavy penetrating mechanisms, and continuous power supply and control support are required to be provided by means of operation ships, so that the system is heavy in whole, poor in maneuverability, large in limitation of sea conditions on operation windows and high in operation cost. Secondly, the physical size and the structural strength of a single probe rod are limited, the types and the number of sensors which can be carried are limited, the observation dimension is single, and multi-parameter and high-density spatial distribution data are difficult to synchronously acquire on the same section, so that comprehensive and three-dimensional monitoring and inversion on regional geological structure variation or physical field evolution cannot be performed. In addition, the sensor is concentrated in a single point or a very small range, the data representation is insufficient, and the sensor is easily influenced by biological adhesion, mechanical stress or connection failure in long-term arrangement, so that the space coverage, long-term continuity and overall reliability of the obtained data are limited.
