| dc.description.abstract | Accurate prediction of ground settlements related to deep supported excavations or foundation works are key in risk assessments of vulnerability of neighboring assets. Several studies show that rotary percussive duplex drilling of casings for tieback anchors and piles can cause substantial local soil volume loss (cavities) around the casings resulting in ground settlements. This paper presents FE back-analysis of a well-documented deep supported excavation in soft clay to investigate the influence from such soil volume loss on the surrounding ground. The analysis demonstrates a simple approach to estimate potential installation effects from overburden drilling by modelling volume loss in specified soil clusters. The method can be implemented in early-planning risk assessments in building projects to assess influence areas and suitability of drilling methods. | |
