Description
Technical Field
The utility model relates to the technical field of ground material test analysis, in particular to a landslide test device for different soil samples.
Background
Landslide refers to landslide of earth and stone blocks sliding down the landslide under the influence of gravity, and mainly refers to deformation and movement phenomena of soil bodies on a damaged sliding surface under the influence of earthquake or local storm. And landslide is caused when the total shear force of the soil body on the sliding surface is larger than the total shear strength of the soil body. Once landslide occurs, landslide of the soil and stone blocks can further cause debris flow, and the scale of the debris flow is different according to the local rainfall condition and the landform condition, so that property loss and casualties with different degrees can be caused. When a mountain is excavated due to the need to build a road or the like, or when a dam, a dyke or the like is built, it is necessary to perform a landslide risk evaluation to determine the stability of the slope. In addition, in areas with relatively high landslide occurrence frequency, the occurrence of landslide is predicted in advance, and corresponding disaster prevention measures are formulated. If landslide cannot be predicted, prevented and controlled in time, not only the life and property safety of personnel can be endangered, but also serious secondary disasters can be caused.
In order to evaluate the stability of the slope and the possibility of landslide, the safety coefficient of the slope needs to be determined in advance (the safety coefficient refers to the ratio of the shearing strength to the shearing stress of the earth and stone when landslide occurs). The safety coefficient is critical to the stability of the determined side slope, however, as the shear strength on the broken surface of the side slope can change continuously along with time, the prediction result is inaccurate only by predicting the concrete time of occurrence of the side slope according to the safety coefficient, and the occurrence of the side slope disaster needs to be judged by combining the evolution behavior of the sliding surface when the side slope is unstable. Because field experiments are significantly affected by surrounding environments and the manufacturing cost of test devices is high, the research in the field is currently carried out by adopting an indoor model test method, for example: a multi-section rainfall induced landslide test device (patent number: CN 210039374U) simulates rainfall induced landslide disasters through a rainfall device, and changes water supply quantity by using an artificial rainfall simulator so as to judge the occurrence time of landslide under different rainfall conditions, but the device cannot monitor the shear plane stress change condition of soil landslide in real time and cannot obtain the safety coefficient of the landslide.
