Abstract：An experiment on fracturing process of cemented soil is conducted to investigate the behaviors of cemented soil under various environmental conditions. The fracturing process of cemented soil is observed in real time using high-precision numeral camera. The surface effects of cemented soil are studied under different ionic strengths，values of pH and chemical solutions. The fracturing behaviors of cemented soil under environmental erosion are analyzed. At the same time，mechanisms of erosion are explained. The results show that environmental erosion has little effects on fracturing process in contrast to evident influence on mechanical strength.
