结合绍兴柯桥万达广场地质情况及荷载特点,对桩型、桩径及地下室防水底板形式等进行了综合考虑及多方案的比较选择,最终选择了钻孔灌注桩桩基承台与无梁防水底板相结合的基础形式。无梁防水底板用有限元软件SLABCAD进行倒楼盖建模计算时,楼面荷载不仅需注意荷载分项系数的准确选取,而且需注意底板自重量的扣除次数。对兼做无梁防水底板柱帽的典型承台计算方法也做了详细介绍。 Combined with the geological conditions and load characteristics of Wanda Plaza in Keqiao, Shaoxing, the pile type, pile diameter and the form of basement waterproofing floor were comprehensively considered and compared with each other. Finally, the pile cap pile foundation and the non-beam waterproofing The basis of the combination of the bottom form. No beam waterproof floor Finite element software SLABCAD inverted floor modeling calculations, the floor load not only pay attention to the accurate selection of load factor, but also pay attention to the deduction from the weight of the floor. The calculation method of the typical cap for the double-column waterproof capless floor cap has also been introduced in detail.
