Observation of Cemented Soil Structures Based on In Situ Test Results

Abstract

There is a significant difference in the behaviour of cemented and uncemented soils, so it is important to detect the cemented structures using the common in situ tests. But, as a result of the implementation of the in situ tests, the structure of the soil and the cementing bonds become damaged. There are lot of recommendations for the interpretation of Cone Penetration Test (CPT) and Flat Plate Dilatometer Test (DMT), and how these are applicable to observe the cementation. The aims of this article are to give a review of these recommendations and to perform the analysis of some CPT tests related to pile load tests with unusual results. In these cases, calcareous medium/high plasticity clay was present in the soil profile.
