Predicting the Stress–Strain Behavior of Alluvial Soil Using Hyperbolic-Weibull Constitutive Model
The shear strength behavior of alluvial sand along the Angat Riverbanks in the Philippines was investigated to determine its applicability as embankment material. From direct shear tests, the dry alluvial soil for three initial relative densities and under three normal effective stresses exhibited peak shear strength and dilatant behavior, indicating a brittle failure. The alluvial soil in dry and saturated conditions manifested a strong shearing resistance of 37.52° and 36.61° angles of internal friction, respectively. A constitutive model based on the combined hyperbolic and Weibull functions was formulated. The results of independent actual values versus predicted values provide a good approximation of the constitutive responses of the alluvial soil, both for dilative and contractive behaviors. The simplicity of the direct shear tests and the efficiency of the constitutive model developed in this study are useful for embankment applications of the alluvial soil and the other similar soil types.
