modular ratio การใช้

• Associating example , the influence factors of the stress ratio of pile and soil are discussed , especially the replacement rate , the modular ratio of pile and soil , deformation modular of gravel pile , reyleigh wave velocity of soil between piles are given more effort
• The analysis show that the influence given by the area replacement rate is very little , while the modular ratio of pile and soil is a important influence factor . the research about the deformation modular of 17 gravel piles show that the variation rage of gravel pile deformation modular is little , so long as the construction quality is good
