Loy Yang Mine Ground Movement Investigation and Modelling: A Case Study

This study used PLAXIS finite-element modelling, calibrated against survey data, to assess ground movement caused by excavation and aquifer depressurisation at Loy Yang Mine.
The analysis predicted substantial horizontal displacement, settlement and mine-floor heave as mining expands eastward to depths of approximately 250 metres.
The findings support safer mine planning and the design and positioning of infrastructure within areas affected by future ground movement.

Soil Improvement by Dynamic Consolidation (A Case Study)

This paper presents the dynamic consolidation of 225 hectares of reclaimed land at the Assaluye petrochemical complex in Iran.
Field testing confirmed effective soil densification to depths of approximately 8–9 metres, improving strength and reducing liquefaction potential.
The treatment reduced the average settlement rate from approximately 50 mm/MPa to 10 mm/MPa, demonstrating its effectiveness for large-scale ground improvement.
