Author : R.P. Martin, K.L. Siu & J. Premchitt


This report is a record of a review of case histories of the use of horizontal drains in slope stabilisation in Hong Kong. It provides a brief account of the history of development and application of horizontal drains in Hong Kong. It presents basic data for 87 sites where horizontal drains were used and discusses in detail eight of the cases with better information. From these selected cases, observations are made on practical aspects of the design, construction, monitoring and assessment of performance of horizontal drains. These observations should be applied in the context of the quality of information available.
