LATERAL EARTH PRESSURE, SLOPE STABILITY AND PILE SHEETING (Sheet piled constructions)

subject

description

This master thesis studies about how the sheet pile walls resist the lateral earth pressures on slope area. Sheet pile walls are one type of construction elements that are built by a continuous interlocking of pile segments side by side to each other. They are embedded in the soils to provide lateral supports by resisting the horizontal pressures released from sea waters, or any other earth masses. Sheet pile walls are flexible retaining systems therefore they can tolerate larger horizontal deformations compared to other types of walls such as stone and concrete. Sheet piles are made up of different types of materials in different forms and sizes. Although steel sheet pile has a higher rate of corrosion property, they are the most used due to its availability in the markets all over the world and its super resistance while being installed by hydraulic pressures. PVC can substitute steel sheet piles concerning environmental impact, sustainability, and maintenance requirements against corrosion. The thesis question is (How can one keep the stability and durability of a sheet piled wall construction on slope areas?) and some sub questions that widen the thesis question are listed as 1. What is the concept of pile sheeting? 2. How can one ensure the stability of sheet piled constructions? 3. How can one select the size and material type of a sheet pile for a certain construction? 4. How can one possibly keep the durability of sheet piled wall constructions? The maximum moment induced by the latera earth pressures, the section of modulus of sheet piles are the key expression for selecting a sheet pile size. However, the environmental conditions, strength sustainability and maintenance requirements have a great role in selecting material type of the sheet piles.
