流变是岩土材料的重要特性之一,许多滑坡在破坏前都表现出明显的流变特性。但在实际工程中对于滑带土体流变特性及其所导致的土体强度变化往往没有较实用的分析预测方法。文章以云南省弥勒县滑石板水库滑坡滑带土为研究对象,通过对滑带土进行三轴蠕变试验及松弛试验,得出土体强度参数随时间变化的拟合曲线方程,为预测滑带土的长期强度提供一定理论依据,亦为评价滑坡的长期稳定性及预测滑坡防治工程的长期效果提供一定的理论基础。
Rheology is one of the most important characteristics of geomaterials, and many landslides show obvious rheological properties before failure. However, in practical engineering, there is often no practical analytical method for the rheological properties of the sliding zone soil and the changes of the soil strength caused by it. In this paper, the landslide slide landslide in Maitreya reservoir in Yunnan Province is taken as the research object. By fitting triaxial creep test and relaxation test, the fitting curves of soil strength parameters with time are obtained. Provide some theoretical basis for the long-term strength of soil, and also provide some theoretical basis for evaluating the long-term stability of landslide and predicting the long-term effect of landslide prevention and control project.
