Abstract
For excavated ground which has been treated with brittle materials, an analysis of the behavior of the earth-retaining structures according to the conventional ground spring method may result in underestimation and the result should be treated with caution as the residual strength is substantially smaller than the peak strength.
This paper proposes a new approach which is able to reflect the strength characteristics of the treated ground, and confirms its apricability through a comparison with the field measured value. Also proposed in this paper is a method to check the thickness of the treated ground
