Project Title:
TUBITAK 1001 - Arching mechanism in soil embankments supported by high modulus columns"

Project Description:
In transportation networks and structures (such as embankments, tunnels, retaining walls, pipelines, etc.), the key characteristic of their mechanical behavior is the arching phenomenon. Arching, which governs the load distribution between structural elements and soil of different stiffness, occurs when there is relative movement between the structural elements and the soil. The main objective of this project is to understand the arching behavior in soils, identify the primary factors controlling this behavior, and establish a means to calculate it based on these factors.

• In our laboratory, a multi-trapdoor physical model is employed in experimental studies to examine the arching mechanism. High-resolution photographs are taken continuously and analyzed using Particle Image Velocimetry (PIV). From these analyses, embankment deformations are determined, and arching structures are identified and monitored accordingly.

Project Tasks:

• You will work with a physical test model that examines the mechanical behavior of granular materials.
• You will help calibrate and use ground pressure sensors and data loggers.
• You will have the opportunity to work with new and interesting techniques, such as Particle Image Velocimetry (PIV), which can analyze the deformation and general behavior of the ground through high-speed images.

Advantages:

• Your name will be included as an author in a paper presented at an international conference.
• By working on an advanced-level research project, you will gain significant experience that will strengthen your academic and professional resume.
• You will be able to experience physical modeling firsthand and learn about academic research processes in depth.

Requirements:

• Enrollment in an undergraduate program in Civil or Mechanical Engineering.
• You should be ready to take over the requirements of the projects, such as due physical effort, proper attention, and care.
