Abstract
At present, there are few technologies applied to in situ observation of seabed deformation, among which the micro-electromechanical accelerometer-array (hereinafter referred to as accelerometers array) is a very advantageous measurement method, with both commercial products and successful application cases. However, the coupling effect between accelerometer-array and surrounding soil and the linkage effect of accelerometer-array itself during the deformation may influence the accuracy and reliability of the measurement data. A simulation test chamber was designed and processed, and four groups of simulation tests were carried out to explore the coupling effect and linkage effect of accelerometer-array in the soil with different degree of consolidation. The results show that the accelerometer-array and the soil coupled well, and the coupling effect is positively correlated with the degree of soil consolidation. The ratio of accumulative deviation to soil lateral deformation is high at the initial stage of deformation (0–50 mm) and reduced with the continuous increase of deformation (> 100 mm). In the process of liquefied soil deformation, the linkage effect of accelerometer array can be ignored, and is negatively correlated with the degree of soil consolidation. A concept to improve the measurement accuracy of accelerometer-array in different seafloor failure deformation modes is proposed. The research results provide references for the modification of accelerometer-array and the improvement for other flexible rod-shaped deformation sensors.
