A large portion of the Yelgun to Chinderah Freeway is located in areas underlain by soft and acidic soils. Construction of the road embankments in these areas presented significant constraints and risks to the project, involving short-term stability, long-term settlement, and durability of structures. Safe and economical soft ground treatment measures were developed to overcome the difficulties and problems related to soft soils. Modern numerical techniques were utilized to model the complex soft ground problems, leading to optimized soft ground designs. Extensive geotechnical investigations, field trials, and instrumentation were implemented to better characterize the soft ground behaviors and thus control and manage risks. The project was successfully completed before the deadline and within the budget. |
