| Abstract: | It make the theoretic basement for determining the bearing capacity of reinforced-expansive soil foundation and make the reference for the engineering design in this thesis, through establishing the formula of limit bearing capacity considering the expansive earth pressure about reinforced expansive soil foundation based on balance theory of no return, which is based on the distribution of expansive earth pressure produced in expansive soils and on the reinforced mechanism and failure one of reinforced-earth. |

| Keywords: | reinforced expansive soil foundation limit bearing capacity dense reinforced-earth spare reinforced-earth |
