Geotechnical Instrumentation for the Yelgun to Chinderah Freway

Dr Jef Hsi

A large portion of the Yelgun to Chinderah Freeway was located in areas underlain by soft soils. Construction of the road embankments in these areas presented significant constraints amd risks to the project, involving short term instability and long term settlement. Due diligence was carried out to ensure development of effective solutions, and control and reduction of risks. Geotechnical instrumentation and monitoring formed a crucial part of the soft ground treatment. The design and construction were constantly reviewd and modified as required in response to the field performance. This process allowed flexibility in design and construction and was provide to be successful and cost effective.
