The great height difference also brings difficulty to the structural design.
Hilly land buildings are often built according to the situation, so that the landform can be fully utilized to connect high and low ground to form a whole, and the building form often forms a semi-basement structure which faces the air by leaning on a mountain. The common basement has soil around, so that horizontal acting forces are mutually offset, and the whole structure is not influenced; the structure of a half basement facing the air while the backer is different from the structure of a common basement, and the structure of the half basement facing the air while the backer is facing the air means that one side of the backer bears huge soil pressure, and the soil pressure has horizontal acting force on the whole building, so that the building can slide and even overturn, and the structure is particularly serious for a land block with large height difference, and the safety of the structure is influenced. The horizontal force against the earth pressure is a major and difficult point in the design of such building structures.
A common method of resisting horizontal forces is to add piles that resist horizontal forces. The resistance of the vertical piles to horizontal force is limited, and a large number of piles are needed when the soil pressure is high, so that the method is not economical; the inclined horizontal pile is difficult to construct and is not suitable for use. In addition, the geological condition of hilly lands is better, the bearing capacity of the foundation is large, and the piling method is not suitable and uneconomical. If break away from retaining wall and building main part and establish ordinary gravity type retaining wall alone, can influence the function of building connection height ground like this, gravity type retaining wall volume is huge, and has certain limitation (gravity type retaining wall should be used for below the 8m difference in height). The large-altitude-difference building structure in the hilly land needs to develop a more applicable and more economical retaining wall.
