The soil movement information over time is required for the design of foundations placed in expansive soils. This information is also helpful for the assessment of pre-wetting and controlled wetting mitigation alternatives for expansive soils. Several researchers during the past fifteen years have proposed different methods for the prediction of the soil movements over time. The available methods can be categorised into (i) consolidation theory-based methods, (ii) water content-based methods, and (iii) suction-based methods. In this paper, a state-of-the-art of the prediction methods is succinctly summarized. The methods are critically reviewed in terms of their predictive capacity along with their strengths and limitations. The review highlights the need for prediction methods that are conceptually simple yet efficient for use in conventional engineering practice for different types of expansive soils.

“…Several researchers tried to predict the volumetric movement of expansive soils analytically (Alonso et al 1999;Briaud et al 2003;Vu and Fredlund 2004;Wray et al 2005;Overton et al 2006;Adem and Vanapalli 2013) and numerically (Vu and Fredlund 2006;Rajeev and Kodikara 2011;Puppala et al 2013;Chittoori et al 2017). Analytical methods of swell prediction are based on moisture/suction variation and constitutive laws that link the soil state variables (Briaud et al 2003).…”

“…Several analytical methods have been suggested by the researchers to estimate the volume change behavior of expansive soils over time (Alonso et al 1999;Briaud et al 2003;Vu and Fredlund 2004;Wray et al 2005;Overton et al 2006;Vu and Fredlund 2006;Adem and Vanapalli 2013). To evaluate the volume change behavior, moisture or suction variation ranges over time and constitutive laws that linked with soil behaviors must be defined (Briaud et al 2003).…”

“…Suction-based methods are the most extensive methods to evaluate the soil movement of unsaturated soils (Richards 1965;Lytton and Kher 1970;Fredlund 1997;Fredlund and Hung 2001;Wray et al 2005;Adem and Vanapalli 2013). Soil suction is more efficient than water-based method because of its low sensitivity to soil material variables and convenient relation with soil parameters (Richards 1974).…”

“…Basic formation of these methods is a proportionate relationship of volume change with suction variation within field condition. Wray et al (2005) used two models to predict the movement of expansive soils. One is moisture flow model to estimate the water flow (Mitchell 1979) and the other model is volume change model to define vertical soil movement incorporated with suction over time (Wray 1997).…”

SUMMARYShrink-swell soils can cause distresses in buildings, and every year, the economic loss associated with this problem is huge. This paper presents a comprehensive system for simulating the soil-foundation-building system and its response to daily weather conditions. Weather data include rainfall, solar radiation, air temperature, relative humidity, and wind speed, all of which are readily available from a local weather station or the Internet. These data are used to determine simulation flux boundary conditions. Different methods are proposed to simulate different boundary conditions: bare soil, trees, and vegetation. A coupled hydromechanical stress analysis is used to simulate the volume change of shrink-swell soils due to both mechanical stress and water content variations. Coupled hydro-mechanical stress-jointed elements are used to simulate the interaction between the soil and the slab, and general shell elements are used to simulate structural behavior. All the models are combined into one finite element program to predict the entire system's behavior. This paper first described the theory for the simulations. A site in Arlington, Texas, is then selected to demonstrate the application of the proposed system. Simulation results are shown, and a comparison between measured and predicted movements for four footings in Arlington, Texas, over a 2-year period is presented. Finally, a threedimensional simulation is made for a virtual residential building on shrink-swell soils to identify the influence of various factors.
