摘要
结合国标《建筑地基基础设计规范》(GB5007-2002)中所阐述的确定地基承载力的方法,定性的分析了在弹塑体假定条件下,地基承载力受地下水位在基底塑性区开展深度范围内变化时的影响程度,简述了地基承载力受地下水的影响程度与基底土层的粘聚力 C、土的内摩擦角Ф、及上部结构间的关系,指出地下水位在枯水期和丰水期的上下波动对地基的稳定性存在不利影响,而在实际工程设计中此影响往往容易忽视,希望设计者要根据实际情况,充分考虑到这种不利因素,保证上部结构的安全与稳定。
Combining with gountry standard CODE FOR DESIGN OF BUILDING FOUNDATION(GB5007- 2002); The article analyses the influence of subgrade bearing capacity when level of underground water change within the scope of foundation bottom below plasticity district. The article also expresses the relation between the influence degree and adhesive force(c),inner frictional angle(Φ),upper part structure. The disadvantage effect of upper and lower fluctuations of the water table in wet season and dry season on stability of the subgrade is pointed out. This kind of effect was often neglected in the engineering design. So, the designers are expected to think over this disadvantage effect adequately and ensure the safety and stability of upper structure according to the effect.
