Abstract

In the process of offshore exploitation, marine geological disasters such as seabed subsidence and submarine landslide threaten the service safety of offshore structures. The generation and development of shear zones in marine soil are the early characteristics of these marine geological disasters. Monitoring the dynamic change of shear zone volume fraction in marine soil in real time can reflect the instability of marine soil and then warn the geological disasters in the process of marine development. Marine resistivity monitoring has the advantages of a large monitoring range and real-time measurement, so it has good application potential. However, for the generation and development of shear zone in marine soil under load, the corresponding variation characteristics and the quantitative evaluation method of marine soil resistivity on this process are not clear at present. In this study, the remolded marine soil samples were configured based on the in situ sampling results of Hangzhou Bay, carried out resistivity triaxial compression experiments on marine soil samples with different dry density and clay content, and obtained the resistivity monitoring data of shear zone evolution process of different marine soil samples under vertical load. The results show that the resistivity change of marine soil with different dry density and clay content under vertical load is controlled by the volume fraction evolution of soil shear zone and has similar characteristics. Moreover, a method for quantitatively interpreting the volume fraction change of shear zone from resistivity monitoring data is proposed.
