Special Issue Information

Dear Colleagues,

The ocean is the cradle of life and is rich in natural resources. With the worldwide boom in exploration and application of ocean resources, a dramatically increasing amount of coastal engineering and offshore engineering facilities have been constructed in the last few decades. The rapid development of human economic activities and the global climate change are having a significant impact on the marine environment, resulting in frequent geological disasters. Under this circumstance, there is an urgent demand for a platform for scientists and engineers to share their state-of-art research outcomes in the field of Marine Engineering Geology.

The 2nd International Symposium of Marine Engineering Geology (ISMEG 2019) will be held in Dalian, China, on 18–20 October 2019. The theme of this symposium is “Exploration of Marine Resources and Marine Engineering Geology”. It will provide a great opportunity for scientists and engineers worldwide to discuss recent advances, share their knowledge, and identify future research directions in the field of Marine Engineering Geology. Seven topics will be discussed in the symposium: 1) Engineering Properties of Marine Soils; 2) Marine Geological Hazards and Preventions; 3) In situ Exploration, Monitoring, and Physical Modelling; 4) Hydrodynamics and Environmental Interaction; 5) Exploration of Gas Hydrate; 6) Offshore Foundations; 7) Pipe–Soil–Fluid Interaction.

ISMEG 2019 will invite top researchers worldwide to submit papers, share their research outcomes, and report recent advancements on the key topics mentioned previously. It is expected to receive more than 50 contributions from high-profile senior academic researchers and young researchers, on the basis of previous experience.

The objective of this Special Issue is to publish high-quality papers from ISMEG 2019 participants. The submitted papers will go through JMSE peer-review process, like regular papers. It is believed that this Special Issue will provide a timely overview of marine engineering geology and geotechnics of recent cases, theoretical advances, laboratory and field testing, design methods, and the potential for further development of these disciplines. Moreover, with a timely and well-organized publication, the state-of-the-art data, analyses, and methodologies presented in this Special Issue could be of great interest to all the readers of Journal of Marine Science and Engineering.

Most existing research on the stability of spudcans during reinstallation nearing footprints is based on centrifuge tests and theoretical analyses. In this study, the reinstallation of the flat base footing, fusimform spudcan footing and skirted footing near existing footprints are simulated using the coupled Eulerian–Lagrangian (CEL) method. The effects of footprints’ geometry, reinstallation eccentricity (0.25D–2.0D) and the roughness between spudcan and soil on the profiles of the vertical force, horizontal force and bending moment are discussed. The results show that the friction condition of the soil–footing interface has a significant effect on H profile but much less effect on M profile. The eccentricity ratio is a key factor to evaluate the H and M. The results show that the geometry shape of the footing also has certain effects on the V, H, and M profiles. The flat base footing gives the lowest peak value in H but largest in M, and the performances of the fusiform spudcan footing and the skirted footing are similar. From the view of the resultant forces, the skirted footing shows a certain potential in resisting the damage during reinstallation near existing footprints by comparing with commonly used fusiform spudcan footings. The bending moments on the leg–hull connection section of different leg length at certain offset distances are discussed. Full article

Marine soft soil foundation is a double-layer foundation structure with a crust layer and soft substratum. Moreover, it is common that there are various forms of drainage. Accordingly, based on Terzaghi’s consolidation theory and the continuous drainage boundary conditions theory of controllable drainage conditions, an improved double-layer soil consolidation theory considering continuous drainage boundary conditions was proposed. To improve the computational efficiency and accuracy, the Laplace transform and the Stehfest algorithm was used to deduce the numerical solution of the improved double-layer soil consolidation theory considering continuous drainage boundary conditions and to compile a computer program. Subsequently, the theory was validated and analyzed by the degenerated model of the perfectly permeable boundary conditions and the semi-permeable boundary conditions, respectively, which showed that this theory has higher accuracy. Simultaneously, the analysis of double-layer consolidation settlement under continuous drainage boundary conditions for marine soft soil foundation of Guangxi Binhai Highway was carried on. The result showed that the consolidation settlement calculated by the improved double-layer consolidation theory presented is basically consistent with the field measurement results, and that the correlation coefficient between them is higher. Accordingly, the research results can provide useful basic information for marine soft foundation engineering. Full article
