Deformation foundation settlement calculation method based on building inherent settlement
Foundation settlement calculation method comprises the steps that a plurality of dewatering wells are arranged on the upstream face and the downstream face of a building foundation around a foundationpit; a settlement calculation model of buildings around the foundation pit is established according to the positions of the two rows of cast-in-situ bored piles and the positions of the dewatering wells; an unwatering part and a saturated part are separated from a precipitation curve, and the additional load of the unwatering part and the additional load of the saturated part are correspondinglycalculated; the settlement amount S<1> of the unwatering part is calculated according to the additional load of the unwatering part, and the settlement amount S<2> of the saturated part is calculatedaccording to the additional load of the saturated part; and the total settlement S = Xi (S<1> + S<2>) of the building foundation around the foundation pit is calculated. The deformation foundation settlement calculation method based on the building inherent settlement has the advantage that a calculation result is more accurate.
本发明涉及一种基于建筑物固有沉降的变形基础沉降计算方法，涉及沉降计算的技术领域。它包括在基坑周边建物基础的迎水面和背水面均布置多个降水井；根据所述两排钻孔灌注桩的位置以及降水井的位置建立基坑周边建筑物沉降计算模型；在降水曲线上分出疏干部分以及饱和部分，分别计算疏干部分的附加荷载，以及饱和部分的附加荷载；根据疏干部分的附加荷载计算疏干部分的沉降量S1，根据饱和部分的附加荷载计算饱和部分的沉降量S2；计算基坑周边建物基础的总沉降S总＝ξ(S1+S2)。本发明具有计算结果更加准确的优点。
