导言:滑坡对工程建筑、农用耕地和自然环境造成的破坏损失相当于开发利用斜坡费用的总和。研究滑坡现象的动态是评价滑坡的实际危害性和设计滑坡治理措施所必须的。这就意味着要确定斜坡的稳定性和取得土体位移的速度和方向以及它们的应力状态随时间变化的资料。研究滑坡形变的现有的工程地质方法在斜坡地表的调查中是最有效的,但在长期和系统的观测不同深度土体的位移方面没有什么用途。
Introduction: Landslides cause damage to engineering construction, farmland and the natural environment at a cost equivalent to the sum of the costs of development and utilization of slopes. Studying the dynamics of landslide phenomena is necessary to evaluate the actual hazards of landslides and to design landslide control measures. This means obtaining information on the stability of the slopes and on the speed and direction of the soil displacements and their stress state over time. Existing engineering geologic methods of studying landslide deformation are most effective in the investigation of slopes and landslides but are of little use in the long-term and systematic observation of the displacement of soils at different depths.
