Special Issue Information

Dear Colleagues,

Encompassing over 71% of the Earth's surface, oceans stand as a vast realm brimming with resources, challenges, and prospects. The intricate interplay among geotechnical engineering, ocean engineering, and the tenets of sustainability has evolved into a central focus, particularly in the face of escalating environmental concerns and the demands of a growing global population. Emphasizing the importance of the research area could help to improve climate resilience, sustainable resource extraction, biodiversity preservation, economic prosperity and innovation and exploration.

This Special Issue aims to comprehensively address every facet of geotechnical engineering (foundation support structures on land and on the seabed, such as high-rise buildings and bridges and offshore installations such as platforms, pipelines and bottom structures) and ocean engineering (coastal structures, offshore platforms and other ocean systems such as underwater systems and ocean wave energy conversion systems) that will potentially contribute to sustainable design and application. In addition, topics related to environmental and economic issues are welcome, as well as original research articles and reviews. Research areas may include (but are not limited to) the following:

  • Soil and rock mechanics;
  • Foundation engineering, e.g., shallow and deep foundations;
  • Retaining structures and slope stability;
  • Geotechnical earthquake engineering;
  • Ground improvement techniques;
  • Underground construction and tunnelling;
  • Reliability analysis in geotechnical engineering;
  • Coastal engineering, e.g., scour, erosion;
  • Offshore engineering, e.g., platform;
  • Marine renewable energy, e.g., offshore wind;
  • Marine sedimentology;
  • Subsea engineering, e.g., pipelines, anchors;
  • Marine instrumentation and sensors;
  • Marine environmental engineering;
  • Offshore installation;

We look forward to receiving your contributions.

In order to respond to the greenhouse effect and achieve sustainable development, microbial-induced carbonate precipitation (MICP) technology based on the spraying method was used as a substitute for Portland cement to reinforce calcareous sand. In order to simulate the tide and determine the suitable concentration, the effects of the initial water level and cementing solution (CS) concentration on the reinforcement were analyzed. The results showed that the distributions of penetration resistance and equivalent calcium carbonate content mainly include two patterns: monotonically decreasing, and initially increasing and then decreasing. The fully saturated case only showed a dense, thin layer of calcium carbonate on the surface, and in the completely dry case, middle cementation was produced. When the initial water level was 0.5 m, the largest range of 60 cm of effective cementation appeared, and both the equivalent calcium carbonate content and penetration resistance were the highest because the microorganisms were more likely to migrate to the particle connection. The calcium carbonate generated by the MICP reaction played a role in increasing the water retention capacity of the sand. As the degree of cementation increased, the SWRC gradually moved up and the matrix suction corresponding to the same volume water content increased sequentially. Increasing the spraying times and the concentration of CS generated more calcium carbonate. The penetration resistance of higher CS concentrations was larger with the same calcium carbonate content. There was a linear relationship between the normalized penetration resistance and the normalized shear wave velocity. Full article
