Abstract:
This paper describes the use of counterfort drainage as a method of providing ground stabilisation. Theoretical design methods are presented together with drawdown tables derived by the author for Auckland soil conditions.
Typical drainage details are given and installation techniques and costs discussed. Monitoring of performance and drawdown results from a case study are presented.
