Correlaciones entre el ensayo de penetración dinámica super pesada, presiómetro de Ménard y verificación con ensayos geotécnicos en suelos arcillosos y limosos del sector Challuabamba-Cuenca

Abstract

The high sensitivity of geotechnical test results to field-collected parameters underscores the need to focus efforts on exploring methods that allow for the correlation of geotechnical parameters based on more accessible sources of information, both from an economic and technical standpoint. This study examines two methods of collecting geotechnical information to establish an initial correlation between parameters obtained through the Dynamic Super Heavy Penetration Test (DPSH) and the Menard Pressuremeter Test (PMT). These methods were applied to five terrains consisting of fine soils in the Challuabamba sector, along with information from the OCP project conducted in the province of Sucumbíos. The collected information was processed using the SUCS method. The intervened terrains were classified as fine, predominantly inorganic silts, with 8 records falling under this classification, in addition to 3 records of clayey soils. The T-Paired test statistical method was employed to verify the equality between the two treatments. Finally, a linear fit was proposed between the results of the bearing capacity of the two mentioned tests. The study found that a combined correlation model of silts and clays does not have a satisfactory fit. However, by limiting the analysis information to silty soils, the fit aligns satisfactorily with the expected results, presenting a Pearson coefficient of 0.95. This leads to the conclusion that an important criterion to consider in the search for correlations in this context is the correct SUCS classification of soils
