  • Modulus of deformation
  • Standard test method for in situ stress and modulus of deformation using the flatjack method
  • Test method for determining the in situ modulus of deformation of rock mass using a radial jacking test
  • Standard test method for determining the in situ modulus of deformation of rock mass using the rigid plate loading method
  • Standard test method for determining the in situ modulus of deformation of rock mass using the flexible plate loading method
  • This kind of structures will cause the principal stress difference bigger due to the sharp changes modulus of deformation between auxiliary core and main core , auxiliary core and upstream and downstream transition materials , which is disadvantage of stress transmission
  • According to elasto - plasticity theory , with the help of finite - method program ansys , the paper undertakes the computer analogue tests about the bearing capacity of pile tip arranged by orthogonal principle , and attains the relations of pile - tip bearing capacity to embedment depth , pile diameter , cohesion , internal friction angle and modulus of deformation . by the means of mathematical statistic , regression equation of the ultimate bearing capacity calculated by finite element method is gained through the regression analysis of 81 group data from the computer analogue tests . by comparison and analysis of the values calculated by finite - element regression equation and the values of in situ loading test , the regression equation is gained which calculates the size effect for base resistance of large diameter pile
  • The settlement is analyzed by using the settlement calculation theory already existed and the pile deformation modulus is researched under the different test conditions . it results in the different pile modulus of deformation that the pile side constraint is different because of the different testing conditions , so the settlement calculation for composite foundation of stone columns must use different computing modes based on the testing conditions
