Suction Analysis at Soil-Geocell Interface for a Clayey Soil
The soils of the Greater Himalayas are predominantly found in Leh and Ladakh, Lahaul and Spiti, and Uttarakhand's upper ranges. The humidity regime is erratic. The arid zone begins from Baralacha pass in Lahaul and extends throughout the Spiti valley in the Himachal Pradesh district of Lahaul and Spiti. The purpose of this study is to establish the suction value of soil taken from the arid zone of the Spiti valley during various freezing–thawing cycles, taking into account the climate variations of the Spiti valley. The most basic and important parameter that impacts the behaviour of an unsaturated soil is suction. Before doing further tests such as shear and permeability, it is critical to know the suction value of an unsaturated soil. In a nutshell, it is the negative pore water pressure in partially saturated soil expressed in terms of water column height. The study employed the filter paper method as a cost-effective way to assess suction. It is the only approach that can determine both contact and noncontact suction. To get a wide range of suction, soil specimens were treated to 0, 1, 3, and 5 freezing–thawing (F-T) cycles for various degrees of saturation, and soil freezing characteristic curves (SFCC) were developed for all F-T cycles. For each SFCC, the data obtained from the experiments revealed the best fitting values using the Fredlund and Xing model.
