摘要:地基基础设计主要包括地基承载力计算、地基变形计算和基础设计计算。承载力计算中要涉及到基底压力Pk的确定和承载力深度修正;变形计算要求基底附加压力P0;基础设计计算需要确定基础反力。当地基中存在地下水时,基底压力、基底附加压力、基础反力的计算,以及对地基承载力进行深度修正就变得比较复杂。本文通过讨论地下水对基底压力、基底附加压力、基础反力和承载力深度修正的影响,给出了上述设计参数的计算方法。

Abstract: Building foundation design includes the calculations of subgrade bearing capacity, subsoil deformation and foundation design. Bearing capacity is involved in the determination of base pressure Pk and depth correction; Deformation calculation requires solution of base supplementary pressure P0; The foundation reaction force need to be identified in the calculations of foundation groundwater exists in the subgrade foundation soils, the calculation of base pressure, foundation reaction force, base supplementary pressure and that how to correct depth e plicated.
