Abstract: A comprehensive analysis of the design of the externsl wall of basement was done, include requirements for concrete durability, waterproof, anticorrosive, anti freeze and crack control design of the externsl wall of basement; the externsl wall of basement outdoor floor live load value, lateral earth pressure and water pressure calculation formula; underground water level conditions affect the level of partial load coefficient value; the externsl wall of basement of the load diagram design simplified; calculation principles of the externsl wall of basement, calculation method and design of deep beam; the externsl wall of basement thickness of protective layer, minimum wall thickness and reinforcement design requirements. Finally to the externsl wall of basement waterproof design, structural design, anti floating design proposed improved method, there are some reference values and practical significance for structure designer.

Keywords: environment class; impermeable grade; frost-resistance level; lateral earth pressure; ground water pressure; thickness of concrete cover
