Stochastic modeling of volume changes in expansive soils
- 4 Downloads
Stochastic analysis procedure was developed to predict the probability and range of volume changes in expansive soils. The plastic limit is an appropriate datum for estimating volume changes in the absence of continuous water content data. Results indicated that the soil usually exhibits swelling (30 mm) due to the prevalent dry conditions. The volume changes ranged between − 44 and + 104 mm for the investigated soil. Similarly, the likelihood to have − 30, + 30, and + 60 mm volume change was 5, 50, and 20%, respectively.
