边坡滑移面软弱夹层时间效应与相关特性的试验研究

The non-linear hereditory creep equation and the related characterics analysis for intercated weak layer of slide-plane

利用陈氏循环增量加载方法 ,对涔天河水库雾江段古滑坡面软弱夹层进行单剪蠕变试验 ,通过对试验结果的分析 ,发现其具有明显的非线性流变特性 .基于遗传蠕变理论建立了非线性遗传蠕变方程 ,并对软弱夹层长期强度的求解方法及剪胀性能进行详细的论述 ,为雾江滑坡体长期稳定性分析及滑移时间效应的研究提供了理论依据 .图 4 ,表 3,参

In this paper ,the single shear tests for the intercalated weak layer of Wujang old sliding plane beside the Qintian river reservoir are conducted by using the Chen's loading method .After studying the results of test, the non linear creep of the interacted weak layer was discovered .On the basis of the hereditary creep theory ,a non linear hereditory creep equation is established ,then , the solution method of long term strength and the shear expand properties are discussed in detail so as to present a theory to analyse the long term stability and study the sliding time dependent behaviors.4figs.,3tabs.,5refs.
