| Abstract |
Current study provides comprehensive insights into the estimation of blast wave parameters within three distinct anisotropic media, namely transversely isotropic (Cadmium Sulphide CdS), monoclinic (Lithium Tantalate LiTaO3), and orthotropic (Ammonium Dihydrogen Phosphate ADP). Within the domain of blast modeling, there remains a significant gap in understanding the impact of surrounding media anisotropy—a crucial aspect often disregarded by numerous researchers. Acknowledging anisotropy holds paramount importance in studying the blast characteristics, the present work explores the velocity profiles of seismic quasi waves within the aforementioned anisotropic media, laying the groundwork for subsequent analyses estimating Scaled Peak Particle Displacement (SPPD) and Peak Pressure (PP). These parameters are evaluated using the Smith and Hetherington’s model, and relying on experimental Peak Particle Velocity (PPV). Furthermore, the study investigates the influence of various sand types, ranging from very dense to loosen, on PP and SPPD within the context of the aforementioned anisotropic media. Additionally, the research entails the estimation and numerical simulation of underground blast parameters, along with the Reflection and Transmission (RT) coefficients relevant to scattering at the interface between two dissimilar media. The findings bear significant relevance in the field of geotechnical engineering, ground shock estimation, mining, particularly in predicting how various sand types respond under diverse loading conditions and external stresses. |
