Sample interview questions: Have you worked on projects involving geotechnical analysis for railway and transit bridge rehabilitations? Can you provide examples?
Sample answer:
Yes, I have extensive experience working on projects involving geotechnical analysis for railway and transit bridge rehabilitations. One of the notable projects I was involved in was the rehabilitation of a railway bridge that had suffered significant structural damage due to soil settlement and erosion.
In this project, my role as a geotechnical engineer was to assess the geotechnical conditions surrounding the bridge and develop appropriate recommendations for its rehabilitation. I conducted thorough site investigations, including geotechnical drilling and sampling, to understand the soil properties, groundwater conditions, and any potential geological hazards that could affect the stability of the bridge.
Based on the findings from the site investigations, I performed detailed geotechnical analysis using specialized software to assess the structural integrity of the bridge and determine the required remediation measures. This involved analyzing the soil-structure interaction, evaluating the bearing capacity of the foundation soils, and assessing the potential for slope instability or settlement.
One of the key challenges in this project was the presence of soft clay soils in the vicinity of the bridge, which posed a risk of differential settlement. To mitigate this risk, I recommended the use of ground improvement techniques, such as deep soil mixing or stone columns, to increase the strength and stability of the foundati… Read full answer
