“…An example is the description of continuous changes in undrained shear strength in the sublayer using the parameter from the CPTU test and supplementing this information in places where only the DMT test was performed. In the case of subsoil from Poland, these dependencies have significant limitations to the dependencies proposed in the world literature (Lechowicz et al 2011, Młynarek et al 2016, 2017, 2018. With such limitations one should also count in relation to the functional relationship between the parameters q t and K D .…”

This paper presents the correlation of soil parameters obtained from the dilatometer of the Marchetti (DMT) and the cone penetration tests (CPT). The data for the development of these correlations come from four experimental sites of the Department of Geotechnical Engineering of the Warsaw University of Life Sciences – SGGW: test embankment in Antoniny, and the Koszyce and Nielisz water dams, Stegna test site, WULS-SGGW Campus. Additionally, the relationship between the soil behavior type classification index (Ic) from the Cone Penetration Test (CPT) and the material index (I D) from the dilatometer test (DMT) based on the Robertson method, modified in this paper, is presented. Finally, a new soil behavior type classification chart was presented, allowing to determine not only the type and condition of the soil, but also the stress history (OCR).

Warstwa gruntów słabonośnych ma miąższość od 3 do 5 m; grunt jest lekko prekonsolidowany (Rabarijoely, 2000;Lechowicz, Rabarijoely i Szczypiński, 2004;Rabarijoely i in., 2008).

“…(5) Zależność (5) funkcjonuje łącznie z wprowadzonym przez Marchettiego warunkiem I D < 1,2, a stosowanie tego wzoru w przypadku utworów silnie prekonsolidowanych nie daje wiarygodnych wyników. Wynika z tego, że kolejnymi krokami w rozwoju podejmowanej analizy i poszerzenia horyzontu doświadczeń powinno być ukierunkowanie na wprowadzenie odpowiednich współczynników w odniesieniu do gruntów silnie prekonkolidowanych i zastąpienie stosowanych dotychczas, często analizowanych w dostępnej literaturze (Lechowicz i Rabarijoely, 2000;Lechowicz, Rabarijoely, Galas…”

“…Comprehensive studies have been performed to improve some of the original correlations proposed by Marchetti. Numerous investigations have been made to expand the application of DMT in geotechnical engineering [8][9][10][11][12][13][14][15][16][17]. In most cases, the relationships used to evaluate geotechnical parameters from the dilatometer test such as the corrected first pressure 2 of 19 reading p o or the corrected second pressure reading p 1 , or index parameters such as the material index I D , horizontal stress index K D , and dilatometer modulus E D , are commonly applied.…”

The undrained shear strength in cohesive soils can be evaluated based on measurements obtained from the standard dilatometer test (DMT) using single- and multi-factor empirical relationships. However, the empirical relationships presented in the literature may sometimes show relatively high values of the maximum relative error. The add-on seismic module to the seismic dilatometer test (SDMT) extends parameters measurable in a standard dilatometer test by the shear wave velocity Vs as an independent variable. Therefore, a method for evaluating the undrained shear strength in cohesive soils based on data obtained from the seismic dilatometer test is presented in this study. In the method proposed, the two-factor empirical relationship for evaluating the normalized undrained shear strength τfu/σ’v is used based on independent variables: The normalized difference between the corrected second pressure reading and the corrected first pressure reading (p1 − po)/σ’v and the normalized shear wave velocity Vs/100. The proposed two-factor empirical relationship provides a more reliable evaluation of the undrained shear strength in the tested Pleistocene and Pliocene clays in comparison to the empirical relationships presented in the literature, with a maximum relative error max RE at about ±20% and the mean relative error RE at about 8%.
