| Abstract: | The unloading earth pressure coefficient at rest is discussed by studying on the variation of lateral stress due to vertical stress reduced,with the aim to emphasized that the pressure coefficient is not constant.Loading stress condition or unloading stress condition should be decided before selecting rightly the pressure coefficient. |

| Keywords: | lateral stress vertical stress unloading soil earth pressure coefficient at rest |
