The application of the cumulative drawdown method in designing of groundwater lowering system - Golden Hill project

Abstract

The presence of groundwater can lead to troublesome conditions when construction operations are to take place below the original groundwater level. There are several techniques or methods available for designing of groundwater lowering systems for a construction project. The selection of a technique or techniques appropriate to a particular project at a particular site or country will depend on many factors. The basic designer's "tool kit" -the formulae and concepts used in routine designs -are presented and their application discussed. By the case of Golden Hill project, the author has analyzed the details of the conceptual model, then selected the cumulative drawdown method to design of groundwater lowering system for particular engineering geologicalhydrogeological at District 1, Ho Chi Minh City, Viet Nam. The paper does not merely cover the numerical aspects of design, but also discuss some of the issues over which "engineering judgement" must be exercised.
