Method for providing foundation horizontal constraint for building structure
The invention relates to a method for providing foundation horizontal constraint for a building structure, and the method is characterized in that the structure comprises an independent foundation and a prestressed rock anchor connected to the foundation, and the tension design value of an anchor rod needs to meet the following condition: [mu]* (Fp + Fk + Gk) < Vk. p is the maximum pressure value (kPa) of the edge of the foundation floor corresponding to the standard combination of action; p is the minimum pressure value (kPa) of the edge of the foundation floor corresponding to the standard combination of actions; G is the self weight of the foundation and the soil weight (kN) on the foundation; F is a vertical force value (kN) transmitted to the top surface of the foundation by the upper structure corresponding to the standard combination of the action; M is a torque value (kN.m) acting on the foundation bottom surface corresponding to the acting standard combination; V is a horizontal force value (kN) acting on the foundation bottom surface corresponding to the acting standard combination; F
is the tension value (kN) of the pre-stressed anchor rod; A is the area of the bottom surface of the foundation, B * H (m<2>); W is the resistance moment (m<3>) of the foundation bottom surface. F is the characteristic value (kPa) of the bearing capacity of the foundation; and [mu] is the friction coefficient of the substrate.
本发明涉及一种为建筑结构提供基础水平约束的方法，其特征在于：该结构包括独立基础，以及连接于基础的预应力岩石锚，锚杆的拉力设计值需要满足下列条件：μ×(Fp+Fk+Gk)＜Vk。pk,max:相应于作用的标准组合时，基础地面边缘的最大压力值(kPa)；pk,min:相应于作用的标准组合时，基础地面边缘的最小压力值(kPa)；Gk:基础自重和基础上的土重(kN)；Fk:相应于作用的标准组合时，上部结构传至基础顶面的竖向力值(kN)；Mk:相应于作用的标准组合时，作用于基础底面的力矩值(kN·m)；Vk:相应于作用的标准组合时，作用于基础底面的水平力值(kN)；Fp:预应力锚杆的拉力值(kN)；A:基础底面面积，B×H(m2)；W:基础底面的抵抗矩(m3)。fak:地基承载力特征值(kPa)；μ:基底摩擦系数。
