摘要

基础是建筑的一部分,它将由基础支撑的上部结构的荷载以自重传递到其下方的土壤和岩石中。钻孔灌注桩基础规划的目的是设计公寓楼内基础的尺寸,计算轴向和横向承载力,计算沉降,计算所使用的配筋,计算钻孔灌注桩基础施工所需的费用。公寓楼的钻孔桩基础采用直径0.5米的圆形基础,深度21米,位于沙土上。钻孔灌注桩轴端承载力采用Reese & Wright法,计算值为70450吨,桩的极限承载力为451766吨。Evans - Duncan法单桩侧向承载力为16359吨,群桩最大侧向承载力为36809吨,最大挠度值为1419 mm。基于计算结果的钻孔灌注桩基础参照《建筑结构混凝土要求》SNI 2847:2013,纵向钢筋采用7D19钢筋,螺旋钢筋采用D16-40钢筋。基础及承台预算计划为10.704.000.000卢比。

PERENCANAAN FONDASI TIANG BOR PADA TANAH LANAU UNTUK GEDUNG APARTEMEN 20 LANTAI
Foundation is the part of the construction that transmits the load of the superstructure supported by the foundation with its own weight into the soil and rock that lies below it. The purpose of bored pile foundation planning is to design the dimensions of the foundation in the apartment building, calculate the axial and lateral bearing capacity, calculate settlement, calculate the reinforcement used and calculate the cost required for the construction of the bored pile foundation. The bored pile foundation in the apartment building used a circular foundation with a diameter of 0,5 meters which has a depth of 21 meters and located on sandy soil. The axial end bearing capacity of the bored pile uses the Reese & Wright method with a calculated value of 70,450 tons and the ultimate pile bearing capacity of 451,766 tons. Lateral bearing capacity of a single pile using the Evans and Duncan method is 16,359 tons and the maximum lateral bearing capacity of the group is 36,809 tons and the maximum deflection value is 1,419 mm. The bored pile foundation based on the calculation results refers to SNI 2847:2013 concerning Requirements for Structural Concrete for Buildings, for longitudinal reinforcement using 7D19 reinforcement and for spiral reinforcement using D16-40 reinforcement. The budget plan for the foundation and pile cap is Rp. 10.704.000.000.
