    Abstract
  • The foundation bearing capacity evaluation of highway engineering in loess area mainly relies on the evaluation standards of architecture, railway and other similar fields, they only provide a formula or bearing capacity table based on whole loess area, which can not meet the needs of highway engineering. Based on analyzing the data of actual plate loading test, the loess areas were divided into four sections according to their bearing capacities, the nonlinear regression relationship formulas were established between loess foundation bearing capacities and water content, liquid limit, void ratio. Applied result shows that the relative errors of the bearing capacities computed by the formulas are less than 10%, compared with other standard methods, the formulas are feasible. Meanwhile, the formulas are revised according to the width, relative distortion, rigidity and flexibility of subgrade.
