Proceedings of the 2018 Sydney Symposium

This document contains the accepted papers submitted and peer reviewed for the 22nd annual symposium organised by the Sydney Chapter of the Australian Geomechanics Society (AGS). It is hoped that the symposium will keep practicing geotechnical engineers, engineering geologists, and other engineering professionals informed of recent developments in this field. It also recognises the need to gather the experience of those practicing throughout Australia and to allow transfer of knowledge and sharing of their experiences.

These symposia continue to be one of the best forms for bringing together the key stakeholders of the Australian geological and geotechnical community. The main objective of the symposium, held on 16 November 2018, is to present overviews of current geotechnical investigation and instrumentation challenges, state-of-the-art practices, innovative technologies, new research results and case histories demonstrating applications of advanced techniques and cost effective approaches in site investigation and verification of long-term performance of earth and earth supported structures. Papers are invited on geotechnical aspects of site investigation, real time monitoring and new insights into experiences, technologies and strategies.

This symposium is the cooperative effort of many authors and qualified reviewers. The editors and organising committee wish to thank the authors, who have generously contributed their time to prepare the various papers and the colleagues of the authors, who have assisted with time, secretarial, drafting and other facilities. Appreciation is also extended to our sponsors for their support. Without them, the Symposium would not be possibly the best ongoing forum for the Australian Geomechanics and groundwater community.
