Study on the Influence of Structural Design and Selection on Basement Construction Cost
This paper mainly analyzes the cost of different types of basement floor with different load and soil cover thickness.The results show that the total engineering cost of large slab without secondary beam per unit area is the lowest under the conditions of civil defense load and machine room load.Under the loading condition of garage,the total engineering cost of one-way secondary beam is the lowest.Under all load conditions,the total engineering cost per unit area is the highest.The total engineering cost of all types of basement floors increases first,then stabilizes and then increases with the increase of soil cover thickness.When the thickness of soil cover is less than 2mm,the total engineering cost of large-plate non-secondary beam is the lowest.When the covering thickness is more than 2mm,the total engineering cost of the cross beam is the lowest.
