Influence of Swelling Pressure on Pore Water in Embankment Core with Swelling Clay Soil
Abstract Swelling clay soil used to fill at core of and used to waterproof for soil dam will swell and increase volume when soaked. This expansion status created the expansion pressure inside dam, increased volume of dam, and harmed the construction. It needs a cover soil to balance and keep the volume of core from expansion due to swell, make soil swelled in cover pressure condition, unchange soil volume, and reduce pore inside soil and permeability coefficient. Swelling pressure reduced pore water pressure and saturated water curve. When swelling finished, permeability coefficient reduced and saturated water curve inside dam raised up, it made pressure to the stability of dam. Changes in swelling pressure depended on type of soil, soil conditions, and density of soil. When swelling finished, friction angle and stickiness of soil increased and the stability of construction did not decrease. Recommendation applies result of this research to constructing earth dam and construction over swelling clay.
