摘要: 采用俞茂宏统一强度理论,运用滑移线场理论对土体材料在无重与有重时的地基极限承载能力进行了分析。通过中间主应力影响参数b的一系列变化,分析了中间主应力对地基强度提高的影响。并以条形基础为例,给出一系列滑移线的统一解,涵盖了现有的各种强度理论所得的结果。Abstract: By using the unified strength theory of Yu.Mao-hong and slip lines theory, the limited bearing capacity of the strip footing with antigravity and ponderability are considered. And also takes account of the effect of the intermediate principal stress to the strength of the shallow strip footing. A strip foundation is taken as an example, and the unified solutions of a series of slip lines are obtained.
