    Abstract
  • Boussinesq combination method, Boussinesq direct method, Boussinesq triangular method and German DB836 method were applied to calculate the foundation additional stress. Composite modulus, modulus calculated by bearing capacity ratio method, and chord modulus were applied as foundation modulus respectively. 12 combining forms were used to calculate the total foundation settlement, and the calculated results were compared with the measured settlements of test sections of high-speed railway. Calculation result shows that when foundation additional stress is calculated by Boussinesq combination method, Boussinesq direct method and German DB836 method, and foundation modulus is chord modulus calculated by composite foundation load plate test, the calculated total foundation settlements are very close to the measured value, and the relative differences are 1.57-9.81%, which can meet the requirement of foundation settlement control for high-speed railway. Therefore, it is recommended to apply additional stress-modulus method to calculate the foundation settlement of subgrade construction for high-speed railway, in which the foundation addition stress can be calculated by Boussinesq combination method, Boussinesq direct method and German DB836 method, and chord modulus is applied as foundation modulus.
