Setup and Calibration of Piles with FBG Strain Sensors in Geotechnical Centrifuge
The research paper presented by Tang, Marshall, Heron, Franza, and Xu at the XVIII European Conference on Soil Mechanics and Geotechnical Engineering in Lisbon discusses the setup and calibration processes involved in conducting centrifuge testing of single piles equipped with fibre Bragg grating (FBG) strain sensors under vertical loads. The study delves into the technical aspects of the experimental setups, highlighting the importance of accurate calibration to ensure precise strain measurements. The results obtained shed light on the influence of these strain sensors on the behavior of the piles under various loading conditions, providing valuable insights for geotechnical engineering applications.
Empirical and Semi-Analytical Methods for Evaluating Tunnelling-Induced Ground Movements in Sands
The journal article authored by Franza and Marshall explores the use of empirical and semi-analytical methods for predicting tunnelling-induced ground movements in sandy soils. The research emphasizes the significance of accurate predictions in tunnel-structure interaction analyses, particularly in assessing potential risks associated with ground movements during tunnelling activities. The study highlights the computational efficiency and reliability of empirical formulas and closed-form solutions, offering valuable tools for engineers and geotechnical experts involved in projects in sandy soil environments.
