摘要
本文详细分析了岩体蠕变变形发展三个阶段的基本特征,提出一种摩擦元件和阻尼元件并联的滑坡中短期预报模型:滑坡发生在加速蠕变阶段,可以用反映摩擦特性和阻尼特性的材料参数不断恶化(文中假设线性变化)予以反映。最后,用三个滑坡实测数据对模型进行了检验。
The fundamental characters at three stages of creep deformation of rock masses are disscussed. A model,a friction element and a dashpot element connected in parallel,suitable for middle
and short time prognosis is suggested——landslide happens at accelerated creep stage and its mechanism
may be described by progressive deterioration (assuming linear change with time) of material parametrs which denote the friction and the dashpot of rock masses. The verification for the model is carried out by comparing the theoretical results with the measured results of three typical landslides.
