    Abstract
  • To overcome the shortcomings of the conventional calculation method of the ultimate soil resistance beneath the cutting curb, a theoretical solution for the ultimate soil resistance beneath the cutting curb is proposed based on the theory of cylindrical cavity expansion considering dilation effects. First, characteristics of the unilateral failure of cutting curb foundation are considered and two cutting curbs are symmetrically spliced into an integral foundation for calculation. Then, the ultimate soil resistance beneath the cutting curb is obtained by using the theory of cylindrical cavity expansion and analyzing the vertical force balance of the soil at the bottom of the cutting curb. Finally, centrifugal model test and field monitoring are used to verify the calculation method. Results show that compared with the results of centrifugal model test, the error of the ultimate soil resistance beneath the cutting curb calculated by this method is 6.6% when the sinking depth of caisson is 36 m. Compared with the results of field monitoring, the error of the ultimate soil resistance beneath the cutting curb calculated by this method is 1.36%, 19.5%, and 9.70% when the sinking depth of caisson is 5 m, 10 m, and 15 m, respectively. The calculated values agree well with the centrifuge model test values and field measured values. This study can provide a new idea for calculating the ultimate soil resistance beneath the cutting curb.
