Prediction of Ground Deformations Due to Excavation-Application to Tunnel Lining Design in Weak Rock
Prediction of ground deformations due to excavations is simulated by three dimensional non-linear finite element analyses. It considers various in-situ ground stress levels, excavation...
Use and Abuse of Settlement Analysis
Terzaghi's concept of settlement analysis included comparison of prediction with reality and investigation of the causes of the differences. Present usage is often limited to prediction....
Settlement of Embankments on Soft Clays
It is now possible to make reliable predictions of settlement of embankments on soft clays. In most situations, where the embankment is designed to resist undrained instability during...
Compressibility of Clays: Fundamental and Practical Aspects
The compressibility of natural clays is influenced by strain rate, temperature, sampling disturbance, stress path and some restructuration factors. The first part of the paper reviews...
Methods to Reduce the Settlement of Embankments on Soft Clay: A Review
New trends have been observed during the past ten years in the practice of settlement control for embankments on soft clays: they include increased use of rigid (piles) or semi-rigid (stone...
