ABSTRACT
Various methods have been proposed to predict the amount of total heave under a given structural load. The following methods, however, are described here.
1. The Department of Navy method (1982) 2. The South African method [also known as the Van Der Merwe method (1964)]
The Department of Navy Method Procedure for Estimating Total Swell under Structural Load
1. Obtain representative undisturbed samples of soil below the foundation level at intervals of depth. The samples are to be obtained during the dry season when the moisture contents are at their lowest.
