ABSTRACT: Interrelationships between the flat dilatometer readings (lift-off pressure, p0, and expansion pressure, p1) and piezocone readings (cone tip stress, qt, and penetration porewater pressures, u2) are explored for three soft clay sites.

Two geoparameters which have not been evaluated in soft to firm clays using the DMT include: (1) effective stress friction angle (φ') and (2) effective cohesion intercept (c'). A methodology for their assessment from DMT readings in clay is proposed herein.

2017年3月8日 · As a result, the derived nexus is explored to predict the effective friction angle of soft to firm clays from DMT data using an existing CPTU limit plasticity solution. Two well-documented case studies are presented to illustrate the reasonable prediction of the effective friction angle in comparison with laboratory anisotropically consolidated ...

2018年9月1日 · Over recent years, several geotechnical explorations in clay deposits have shown that flat dilatometer test (DMT) to provide reasonable estimates of in-situ overconsolidation ratio with depth.

In this paper, the flat DMT test in clay is analyzed using the cavity expansion theory. The soil is idealized as a homogeneous elasto-plastic material described by the MCC model. Both p0 and p1 are analyzed and related to the fundamental soil parameters and the in-situ stress state.
