Power base station large board foundation design

Do substation equipment support structures need a foundation?

For most substation equipment support structures and line support structures, the foundations are required to resist moderate shear forces and overturning moments. For A-frame and lattice-type line support structures, shear, uplift, and compression are typical design loads.

How thick is a power plant foundation?

In the first case (A) of the new power plant foundation, according to design data prepared by the foreign design office, and delivered by the main contractor of the power plant building, the main boiler house foundation represented one large slab which equals 80×50 m in plane and it was from 1.8 m to 2.6 m thick.

How are pole-type line support foundations designed?

For pole-type line support structure foundations, a different method of foundation design is employed. These structures are designed on the basis of yield stress, and appropriate overload factors are applied to the structure loads. To complement these loadings, a foundation design is used utilizing the ultimate strength of the soil. See Figure 7.

Why is reliable foundation of power plant buildings important?

Reliable foundation of the huge power plant buildings is significantly important, due to strategic role of this type of engineering objects in the national economy. Due to importance of the investment and its great costs, all power plant buildings are classified to the third geotechnical category regardless of the soil conditions.
