Abstract
The penetration processing of piezocone penetration test (CPTU) is very important for the analysis of stress-strain of soil bentonite cutoff wall (SBCW) in landfill site. In this paper, CPTU is conducted in the soil bentonite cutoff wall, which is located in Jiangsu province, China. A finite-element procedure is also used to analyze the processing of penetration. The Modified Cam Clay model was adopted to represent the stress-strain response of the soil-bentonite backfills. In this model, a tube was added to the bottom of the cone. This study shows that the largest value of radius stress is in the shoulder of cone. And the influenced domain of PEMAG is ten times of the cone radius.
