The intersection angles of the railway trend and wind direction are different in practical engineering, resulting sand hazard intensities. This research explores characteristics wind-sand flow field, speed change, accumulation near embankments with to reveal formation mechanism hazards. A numerical simulation field around under 15°, 30°, 45°, 60°, 75°, 90° friction speeds is conducted on basis ...

Due to environmental concerns, sustainable ground improvement is considered a critical part of modern infrastructure development. Current policy on environmental sustainability often expects noise-free, chemical-free, and low carbon emission processes, while being economical. In this context, the application of prefabricated vertical drains (PVD) with vacuum preloading is regarded as one of the...

Pseudostatic analysis is one of the simplest approaches used in earthquake engineering to analyze the seismic response of soil embankments and slopes. However, the choice of seismic coefficients used in the analysis can be arbitrary and generally lacks rationale. To investigate this, a parametric study was performed on a soil embankment of varied geometric characteristics and soil properties su...

Figure 2 shows the temperature variation in all reference point sensors and air temperature (TZ) during the last year (August 2015 September 2016). Figure 3 and 4 presents temperatures in CW and CE cross section s sensors to obtain a more clear charts. The sensor UT 17 , which is located about 20cm below the surface, is most sensitive to changes in air temperature. The highest variation of the ...

A fish pond ecosystem on the west coast of Korea was studied for biotic and abiotic factors. The occurrence rate of phytoplankton at the embanked fish farm was 84 times higher to that of shore waters. Phytoplankton species which occurred during the study period were categorized into Cyanophyta, Dinophyta and Bacillariophyta with a total of 26 subgeneric taxa (22 species of Dinophyta, 2 species ...

PURPOSE The aim of the study described here was to report the outcomes of surgery for orbital fat prolapse by conjunctival fixation to the sclera. PATIENTS AND METHODS Twenty-three consecutive eyes of 19 patients with orbital fat prolapse were retrospectively reviewed. All cases were treated with the same simple procedure without resection through conjunctival incision: fixation of conjunctiv...

Piles have been widely used to improve the bearing capacity of soft foundation. The existing research obtains significant findings on load transfer mechanism for rigid piled embankments. However, limited studies focused deep cement mixing (DCM) embankment. To grasp characteristics DCM embankments, a three-dimensional numerical simulation was conducted in this study, which validated by measureme...
