| 摘 要： | 针对广西南宁膨胀土进行固结与蠕变耦合试验研究,探讨了非饱和膨胀土固结与蠕变变形特性,并且得到了对数形式的考虑固结与蠕变耦合的方程,拟合曲线与实测曲线较为吻合.考虑固结效应的蠕变方程比用流变模型得到的蠕变方程更符合膨胀土的实际情况,研究成果为分析膨胀土提供了新的理论方法.

| Abstract: | In view of experimental study of consolidation and creep coupling of Nanning expansive soil, explores the creep and consolidation characteristics of unsaturated expansive soils, obtains logarithmic form equations considering the consolidation and creep coupling, and fiting curves fit very well with the measured curves. Moreover, the creep equation considering consolidation effect is more in line with the actual situation of expansive soil than the equation obtained from rheological model. The research provides a new theoretical method for the deformation analysis of expansive soil. |
