SoilWorks: A Geotechnical Solution for Practical Design
SoilWorks is a software product developed by MIDAS Information Technology Co., Ltd. that is designed to assist engineers and contractors in the geotechnical analysis and design of soil structures, including retaining walls, slope stability, and foundation analysis[^4^]. SoilWorks provides a comprehensive solution for two-dimensional geotechnical problems, covering various domains such as tunnels, slopes, soft grounds, piles, seepage and dynamic analysis[^6^] [^7^]. SoilWorks also conforms to the practical engineering habits and satisfies the design verification requirements[^7^].
SoilWorks is based on the finite element method (FEM), which can simulate the complex behavior of soil and rock under various loading and boundary conditions. SoilWorks supports various material models, such as Mohr-Coulomb, Drucker-Prager, Cam-Clay, Duncan-Chang, Hardening Soil and Rock models. SoilWorks also allows users to define their own material models using user-defined subroutines. SoilWorks can perform both linear and nonlinear analysis, as well as static and dynamic analysis. SoilWorks can also handle coupled problems, such as thermo-hydro-mechanical (THM) and hydro-mechanical (HM) problems[^4^].
SoilWorks has a user-friendly interface that enables users to create and edit models easily. Users can import CAD files, GIS data, borehole data and other external data sources to generate models. Users can also use various tools to modify the geometry, mesh, boundary conditions and loads of the models. SoilWorks has a powerful post-processing module that can display the results in various formats, such as contours, vectors, graphs and tables. Users can also export the results to Excel, Word or PDF files for further analysis or reporting[^4^].
SoilWorks is a reliable and efficient software that can help engineers and contractors to solve geotechnical problems with confidence and accuracy. SoilWorks is compatible with Windows operating systems and requires a license key to activate. Users can download the installation files from the MIDAS website or request a free trial license from MIDASoft[^4^] [^5^].SoilWorks has been used in various projects that demonstrate its capabilities and applications. Some of the projects that used SoilWorks are:
Analysis of a tunnel excavation in soft ground: This project involved the analysis of a tunnel excavation in soft ground using SoilWorks. The project aimed to evaluate the stability of the tunnel face, the ground deformation, and the support pressure during the excavation process. The project used the Hardening Soil model to simulate the soil behavior and considered the groundwater flow and pore pressure distribution. The project also compared the results with field measurements and found good agreement.
Design of a retaining wall with geogrid reinforcement: This project involved the design of a retaining wall with geogrid reinforcement using SoilWorks. The project aimed to optimize the design parameters of the wall, such as the height, length, and spacing of the geogrid layers, and to evaluate the stability and settlement of the wall. The project used the Mohr-Coulomb model to simulate the soil behavior and considered the surcharge load and seismic load on the wall. The project also performed a sensitivity analysis to examine the effects of various factors on the wall performance.
Analysis of a slope failure due to rainfall infiltration: This project involved the analysis of a slope failure due to rainfall infiltration using SoilWorks. The project aimed to investigate the mechanism and triggering factors of the slope failure, which occurred in a highway embankment in Korea. The project used the Cam-Clay model to simulate the soil behavior and considered the coupled hydro-mechanical processes in the slope. The project also reproduced the failure mode and timing of the slope failure and identified the critical rainfall intensity and duration for slope stability.
