## Remarks

・Earth pressure increase on underground exterior wall：ΔP0b
・Above Figure is copied from Reference[1]
・Premise1：The underground exterior wall doesn't move.
・Premise2：The transfer of shear stress between wall and soil will be same as the one between soil and soil.
・Premise3：Poisson's ratio of soil is 0.5
