Special Issue Information

Dear Colleagues,

Energy demand and global climate change have become two of the most significant challenges to human society. This situation forces researchers to develop sustainable and renewable energy resources. Wind energy, a clean, plentiful, and renewable alternative, has promoted a rapid increase in both the installed capacity and the number of wind turbines in recent years. As wind farms move into deeper seas, there continue to be challenges to overcome during construction and maintenance. 

This Special Edition of JMSE will focus on the state of practice and identify current, emerging, and future geotechnical and structural challenges associated with the construction and maintenance of wind farms. The topics are expected to fall into the following areas: 

  • Installation—monitoring, instrumentation, risk management, protections, and case studies;
  • Analysis and design—foundation concepts, design optimization, and standards;
  • Lifetime performance—monitoring, behaviors, digital twins, repair, and disposal.

An elastoplastic analysis scheme for the cylindrical cavity expansion in offshore islands unsaturated soils considering anisotropy is established. The hydraulic properties and anisotropy caused by stress of unsaturated soils are coupled in an elastoplastic constitutive matrix for unsaturated soil to obtain the governing equations for the cylindrical cavity expansion problem, with an analytical solution that utilizes the original hydro-mechanical state of the soil as the initial conditions. Through a comparative analysis with other analytical solutions, the effectiveness of the new solution is verified. Moreover, the swelling response of the cylindrical cavity expansion in unsaturated soils is examined by systematically analyzing different parameters of the surrounding soil. The findings reveal that the development and rate of anisotropy in normal consolidated soil and over-consolidated soil exert a significant impact on the soil’s mechanical characteristics. Nevertheless, the alteration in the model constant h has little effect on the soil’s mechanical characteristics. The analytical solution introduces anisotropy and broadens the expansion theory of unsaturated soils to yield a more comprehensive theoretical framework for the comprehensive analysis of offshore islands’ unsaturated soils.
