the pore structure characteristic parameters were obtained by mercury intrusion porosimetry
and the relationship between compression modulus of soft soil under loading and the pore structure characteristics such as pore volume
pore size and pore connectivity was studied
then the mechanism of compression modulus changing with pore structure of soft soil under loading was discussed. The research shows that a negative power function relation exists between compression modulus of soft soil under loading and the pore structure characteristic parameters including total pore volume content
average pore size and pore connectivity value. And the change process of compression modulus of soft soil under loading with the pore structure might be divided the two stages.
