Centrifuge study on the use of protective walls to reduce tunnelling-induced damage of buildings (2021)
Journal Article

Tunnel excavation in urban areas causes ground movements that could damage existing nearby piled structures. In practice, to protect structures from tunnelling-induced damage, a stiff protective wall can be constructed between the tunnel and the adja...

Geotechnical Characterization of Fine-Grained Spoil Material from Surface Coal Mines (2021)
Journal Article

Coal mines produce large amounts of excavated waste soils, known as spoils. These materials can cover vast areas, are typically dumped in heaps without any treatment and are difficult to exploit for engineering purposes because of their significant v...

Centrifuge Study on the Influence of Tunnel Excavation on Piles in Sand (2020)
Journal Article

© 2020 American Society of Civil Engineers. Tunneling-induced ground movements can affect the equilibrium state of an existing pile, causing uneven settlement among pile groups and damage to connected structures. This paper presents results from five... Read More about Centrifuge Study on the Influence of Tunnel Excavation on Piles in Sand.

Response of Framed Buildings on Raft Foundations to Tunneling (2020)
Journal Article

This paper investigates the response of framed buildings on raft foundations to tunnel construction using geotechnical centrifuge testing.

Assessment of the Posttunneling Safety Factor of Piles under Drained Soil Conditions (2020)
Journal Article

The need to tunnel closely beneath piles is increasing due to the development of urban areas. This poses a risk to the stability and serviceability of overlying structures (e.g., buildings, piers, and piled embankments). The impact of tunneling on pi...
