An investigation is made on the soil pressure in a nine cabin opened bottom elliptical
barrel structure. The calculation models using the penetration of negative pressure method have
been developed. The first calculation model is is for the construction stage involving three zones,
namely, passive, transitional, and active established for the soil pressure in cabins. The other
calculation model is based on the use stage, with the two (passive and active) zones for the soil
pressure in cabins. The height of zones and the theoretical analytical solutions of inner soil pressure
are derived. The analytical formulas of the models are proved using the finite element method and
experimental data, and the formulas are analyzed in the inner soil pressure in the same condition.
The calculation models can be used for other multi-position structural design or construction.
