Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of lightning protection grounding, and more particularly, to a modeling method and system for soil structure of a marine DC grounding electrode region. BACKGROUND
[0002] Before designing a DC grounding electrode, the geological structure and soil resistivity of the location where the DC grounding electrode is to be constructed must be understood, and the soil structure of the electrode site must be surveyed and modeled, so that the characteristic parameters of the DC grounding electrode, such as grounding resistance, step voltage, overflow density, and temperature rise, can be accurately calculated, and the safety design of the DC grounding electrode can be performed.
[0003] In conventional land DC grounding electrode engineering design, the apparent soil resistivity of the electrode site is generally measured by using a four-electrode electric sounding method, and then the soil parameter inversion is performed by using a numerical calculation optimization method according to the measured apparent soil resistivity data, so that a horizontal layered soil structure model of the electrode site can be obtained for use in the design of the grounding electrode.
[0004] Unlike the land DC grounding electrode, the marine DC grounding electrode is located near the sea, and its soil structure is relatively complex, including not only the horizontal layered soil structure on the coast, but also a vertical layered structure between the coastal soil and seawater, which is a composite layered model. The conventional horizontal layered soil model is not applicable. On the other hand, because the resistivity of seawater is generally very low (only about 1 ohm), the resistivity difference between the seawater and the coastal soil is large, and when the four-electrode electric sounding method is used to test the apparent soil resistivity of the coast, the low resistivity of the seawater will provide a good channel for the test current, so that the potential distribution in the coastal soil is quite different from that of the land grounding electrode. In the process of measuring the apparent soil resistivity by using the four-electrode electric sounding method, the test result is obtained indirectly by measuring the potential difference generated by the test current on the ground. Because the low resistivity of the seawater will distort the electric field distribution in the coastal soil, it will significantly affect the test result of the apparent soil resistivity of the coast, making the measurement result much lower than the actual value.
