Calculation process of Baihe power tower steel pipe pile foundation design software
The Electric Power Design Institute and Tower Factory recommend the use of Beijing Baihe Company’s power pole tower steel pipe pile foundation calculation software, steel pipe pile foundation software, and power steel pipe pole foundation
Advantages of steel pipe pile foundation
Steel pipe piles can withstand strong impact forces. Because it can withstand strong impact forces, it has excellent penetration and penetration properties. May be penetrated into a solid support layer as required by design.
, large carrying capacity. Due to the high yield strength of steel, a large bearing capacity can be obtained as long as the piles are sunk on a solid support layer.
, large horizontal resistance and strong resistance to lateral force. Because the steel pipe pile has a large cross-sectional stiffness and a large resistance moment against bending moments, it can withstand large horizontal forces.
, great design flexibility. The wall thickness of each single tube of the steel pipe pile can be changed as needed, and the outer diameter suitable for the design load-bearing requirements can be selected as needed.
The pile length is easy to adjust. When the layer that serves as the pile tip support layer is undulating, the prepared pile will appear to be longer or shorter. Since steel pipe piles can be freely welded to length or cut to length by gas cutting, it is easy to design the length of the pile.
, easy to combine with the upper structure. By pre-welding the steel bars to the upper part of the pile, the steel pipe pile can be easily combined with the upper cap concrete. It can also be directly welded to the upper structure, thus ensuring that the upper and lower parts work together.
Easy to carry, transport and stack.
By inserting a cap on the top of the pile, it resists the horizontal displacement of the pile top and effectively reduces the diameter of the steel pipe pile. There is no reinforcement when being inserted into the cap platform, so the construction is convenient and quick.
, save project costs and shorten the construction period. Steel pipe piles are the most suitable foundation for rapid construction and save engineering costs, so they have high overall economic benefits.
Main functions of the software
The pile types that the software can calculate are single steel pipe piles and single steel pipe piles with caps. The caps are not reinforced.
In the basic parameters, the foundation force and soil parameters need to be input to determine the partitioning status of the pile end partition (open, two-part, four-part, nine-part, closed) and the wall thickness of the steel pipe pile. The software provides three optimization calculation modes, namely, optimal pile burial depth, optimal cap platform size, and optimal pile burial depth and cap platform size together.
The software mainly performs pile side soil stability calculation, pile foundation vertical bearing capacity calculation, pile body bending local stability calculation, pile body composite stress strength calculation. The results generated by the software include basic construction drawings and basic calculation sheets.
