Geotechnical Parametric Estimation and Susceptibility Analysis of Bicol University East Campus, Legazpi City, Albay, Philippines

Natural calamities and geotechnical hazards pose a major risk in maintaining an area’s public safety and its ability to develop economically. Infrastructures must be built sustainably and robustly for sustainable, disaster-resilient structures. Engineering structures must be studied considering geotechnical aspects and risk assessments to comprehend the substrata. This study aims to assess the susceptibility of an area against liquefaction potential or settlement based on geotechnical characterization. Field and laboratory tests were conducted to obtain soil samples and analyzed the susceptibility to liquefaction potential and settlement. The soil was consistently silty sand (SM), with varying shear strength values in each borehole. Results revealed that, BH04, had the highest liquefaction potential and lowest Factor of Safety. Settlement analysis demonstrated that the settlement for BH04 was high compared to other boreholes, which gave the lowest N-Value. This study emphasizes the significance of thorough geotechnical studies for infrastructure sustainability and disaster resilience. The integration of laboratory analyses, field testing, and geotechnical analyses, will enable a thorough understanding of soil behavior and engineering design.
