| Abstract: | The paper makes a theoretical analysis of the principles of pore water dissipation and lateral friction growth.The formula of calculating the latera friction growth around piles with time continuing is regressed from the field data.And based on the expansion theory of cylinder pores,we have inferred the maximum friction growth value. |

| Keywords: | friction resistance expansion theory of cylinder pore TRESOA'S material octahedral shear stress octahedral normal stress |
