Abstract

This GEO Report consists of two Technical Notes in two separate research and development projects carried out by the Special Projects Division in 2000.

They are presented in two separate sections in this Report.

Section 1 : Development of a Portable Soil Sampler for Use at Shallow Depth

For slope investigations, it is often necessary to obtain soil samples for ground characterisation and laboratory testing. This Technical Note presents the work carried out under a pilot project to develop a portable soil sampler to facilitate the work.

Section 2 : Trials of Automatic Piezometric Data Acquisition Systems

This Report presents the benefits of automatic piezometric data acquisition systems and describes the field trials of the three selected systems. It summarises and discusses the results of the trials and the performance of the systems. Conclusions of the trials and recommendations relating to selection of automatic systems, specification of automatic data acquisition service and data quality control are also presented.
