缓变式滑坡岩土体的变形计算

Deformation Calculation of Soil and Rock Masses of Slow-deformation Landslide

本文对缓变式滑坡岩土体的变形机制及变形特征进行了探讨,在分析滑坡监测数据信息的基础上,认为颗粒与颗粒之间挤压而引起岩土体的变形是连续的、缓慢的、长期的,是伴随着整个变形过程的,并选取了与其相关的监测数据,运用线性回归理论中的最小二乘法对主滑段内部颗粒之间的应变进行了求解,并对其变形能进行了计算。

The deformation mechanism of rock and soil masses of slow-deformation landslide is discussed in this paper. On basis of monitoring data, it is considered that the deformation of rock and soil masses due to extrusion among the grains of rock and soil masses is continuous, slow and long-term, and it accompanies the entire defor- mation process of landslide. The relative monitoring data are selected to solve the strain of the grains of rock and soil masses of slow-deformation landslide by the least square method of linear regression theory, and the deformation energy of the rock and soil masses is also calculated according to the strain.
