According to the latest ESI (Basic Science Indicators Database) data, Associate Professor Chao Zhiming, a member of the Marine Structure Disaster Prevention and Marine Resource Development and Utilization team of Professor Shi Danda of the College of Marine Science and Engineering, published a paper entitled Experimental research on temperature - - in the authoritative journal Ocean Engineering. The research paper of Dependent dynamic interface interaction between marine coral sand and polymer layer was selected as an ESI highly cited paper, and the first completed unit of the paper was Shanghai Maritime University. The Marine Structure Disaster Prevention and Marine Resources Development and Utilization team has always focused on the service safety of Marine structures such as ports in Marine and near-shore environments, and has produced a series of high-level achievements in recent years, and five papers have been selected as ESI highly cited papers.
Title: Experimental study on the dynamic mechanical interaction mechanism between Marine coral sand and rough geomembrane considering the influence of temperature
The bearing capacity of Marine coral sand foundation can be significantly improved by laying geosynthetic materials, and the high temperature climate, dynamic stress load and particle size have a great influence on the mechanical mechanism of the interface between Marine coral sand and rough geomembrane, which determines the stability of engineering facilities for laying rough geomembrane coral sand. However, there is a lack of relevant research at present. To solve this problem, a series of cyclic shear tests were carried out on the interface between coral sand and rough geomembrane with different particle sizes in the temperature range of 5℃ to 80℃ by using a temperature-controlled large-size interface dynamic shear instrument developed by the author. The dynamic mechanical characteristics of the interface between coral sand and rough geomembrane were systematically analyzed, and it was found that the influence of temperature on the mechanical behavior of the interface was significant. This finding provides guidance and reference for the type selection and structural design of Marine coral sand engineering laying geosynthetic materials in the future, especially in high temperature or extreme climate conditions. This study provides a new perspective for understanding the interaction mechanism between Marine coral sand and rough geomembrane interface, and is of great significance for improving the design level and safety of Marine coral sand engineering facilities.
