Soil water characteristic curve parameters of collapsible sand in Lambayeque, Peru

Several structures are built on collapsible soils in the mining and petroleum industries civil sites. In order to analyze stability of such structures, one must properly study unsaturated soil behavior. Collapsible frequent sand that susceptible a significant sudden reduction volume upon wetting. An important factor is matric suction, which es related moisture content through water Characteristic Curve (SWCC), SWCC obtained filter paper technique provides valuable relationship between suction unique soils. This measures influence parameters behavior structure soil. Interactions be evaluated as bearing capacities shallow deep foundations linked properties moisture, grade saturation. work has experimentally measured sands, where an oil storage tank will city Lambayeque Peru. Undisturbed specimens from geotechnical exploration campaigns were used. The method used this was proposed by models Brooks-Corey Van Genuchten. Results show consistent values near reported literature.
