摘要
根据工程实例,从覆土厚度、柱网合理布局、材料选用、基础选型、楼盖体系、外墙设计、构造措施等方面对影响地下室造价的诸多因素进行分析,提出了地下室结构设计成本控制的方法。结果表明,当设计中由计算决定配筋量时,钢筋优先采用HRB500,其次为HRB400;就单位面积造价而言,小柱网更经济;小柱网时,无梁楼盖最经济;较大柱网时,长向增加一根次梁时楼盖最经济。最后还提及其他合理结构优化设计方法,以降低工程造价。
According to an engineering example,the factors affecting the basement cost were analyzed from the aspects of soil thickness,reasonable layout of column grid,material selection,foundation type selection,floor system,exterior wall design and constructional detail. The cost control method of structural design of the basement was put forward. The results show that the adoption of HRB500 is preferred to HRB400 when the reinforcement of design is controlled by calculation.The cost per unit area of the basement with small column grid is economy. The flat slab is the most economic when the small column grid is adopted. For large column grid,ribbed floor with one secondary beam in long side direction is the most economic. Other reasonable structural optimization design methods were also presented to reduce the cost.
