COMPREHENSIVE AHEAD PROSPECTING OF TUNNELS IN SEVERELY WEATHERED ROCK MASS ENVIRONMENTS WITH HIGH WATER INRUSH RISK: A CASE STUDY IN SHAANXI PROVINCE

The ahead geological prospecting of severely weathered surrounding rock in a tunnel is challenging due to complex geological conditions.Hence, the best approach is to use a variety of geophysical exploration methods.In this study, we have applied seismic, electrical resistivity (ER), and transient electromagnetic (TEM) methodologies for ahead prosp

Mathematical formulations are crucial in understanding the dynamics of disease spread within a community.The objective of this research is to investigate the SEIR model of SARS-COVID-19 (C-19) with the inclusion of vaccinated effects for low immune individuals.A mathematical model is developed by incorporating vaccination individuals based on a pro
