SYNOPSIS

Part 1:    Inclinometer Measurements and Errors
This presentation examines the errors associated with inclinometer measurements. In recent projects, it was found that while most of the displacement trends indicated expected behaviour in tandem with site activities, there were also instances in which measured displacements did not correspond to nearby activities at site. To understand the shortcomings in the performance of the inclinometers, a detailed investigation was carried and some of the findings are presented. The working principle of inclinometer probe and inclinometer casing is described in detail with illustrations enabling one to understand measurement, data reduction, errors and error correction procedures. Methods of identifying possible causes of errors are presented and actions required to minimize these errors are discussed.

Part 2: “Ground Anchors – from Design to Construction”
Ground anchors have been widely used for temporary support system. Permanent anchors require corrosion protection.  In this presentation design  concepts, code requirements, construction and testing will be discussed.


SPEAKER

Dr. Ganeshan has more than 35 years of experience in all aspects of geotechnical engineering works involving over 100 projects in various parts of Asia. Most of these projects are design and build projects. His involvement in various projects include deep excavations for mass transit structures and basements of various buildings, tunneling and microtunnelling, deep foundations, ground improvement including grouting, ground anchors and, instrumentation for excavations, tunneling, test piles and structures. He has extensive experience in the use of finite element and other numerical programs in the analysis and design of geotechnical structures. Currently he is leading the Tunnel design team for the Deep Tunnel sewerage System Phase 2 which involves 30 km of Deep Tunnel and 70 km of Link Sewers varying in size between 1.5 m and 6 m diameter.
