| 摘 要： | 为了确定修正后的复合地基承载力特征值,论述了天然地基承载力的深宽修正的理论依据,并指出《建筑地基基础设计规范》GB 50007-2002所给出计算方法的局限性。将复合地基分为散体桩、低粘结强度桩和高粘结强度桩复合地基三种情况予以讨论,通过理论推导,提出了复合地基承载力特征值深度修正的计算公式,并结合工程实际进行了验证。

| Abstract: | In order to determine the modified characteristic value of the bearing capacity of composite subgrade, the paper discusses the effects of depth and width of foundation on the bearing capacity of natural soil and points out the limitation of calculating method suggested in China Code for Design of Building Foundation (GB 50007-2002). Then the bearing capacity for composite subgrade is discussed in three conditions, loose column composite subgrade, low bonding strength column composite subgrade and high bonding strength column composite subgrade respectively. A calcution formula for composite subgrade bearing capacity considering foundation depth is provided through theoretical analysis and engineering practice. |
