Embodiment 1

[0061] Embodiment 1: attached Figure 4 Layout plan of smart monitoring sensors for Tailor Rock landslide. The intelligent monitoring and early warning system of the present invention is used to implement monitoring and early warning for Tailor Rock landslide.

[0062] Tailor rock landslide is an ancient rock landslide, located in the low mountain canyon area, on the right bank of Songkan River, with a natural slope of 10°-35°. The main stratum lithology is the residual layer of the Quaternary Holocene slope (Q 4 dl+el ), landslide accumulation (Q 4 del ), slope colluvium (Q 4 dl+dol ); the bedrock is the Upper Shaximiao Formation of the Middle Jurassic (J 2 s) Mudstone and sandstone, the occurrence is N45°E / 10-20°NW. The main axis of the landslide is about 460m long, 90-100m wide, 10-35m thick, and 120×10 in volume. 4 m 3 , is a giant ancient landslide with a main axis direction of about 270°. Since the 1960s, the soil at the front of the slope has been cracked, pa...

Abstract

The invention relates to the field of geological disaster monitoring, particular to an intelligent monitoring and early warning system for the creeping landslide. The intelligent monitoring and earlywarning system comprises a server, a sensor and an information transmission part. The sensor and the server form communication connection by the information transmission part. The sensor includes a displacement sensor and a rainfall sensor. The server includes a contingence angle data processing module and an early warning module; the contingence angle data processing module is used for calculating a contingence angle based on displacement data and determining whether to carry out early warning according to the determination of condition that whether contingence angle exceeds a threshold. According to the invention, a landslide forecasting method for acquiring the landslide approaching contingence angle based on a landslide creep constant-velocity deformation rate is employed; and thus thelandslide approaching contingence angle of the landslide can be obtained only by determining the stage and the constant-velocity deformation rate of the landslide, so that the good early warning andforecasting effects for the destruction and unstability of the landslide are realized.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring, in particular to a creep type landslide intelligent monitoring and early warning system. Background technique [0002] In recent years, with the continuous expansion and construction of railways and highways; excavation of residential buildings and urban tourism development and other constructions, the original geology and landforms have been destroyed to some extent, especially the deforestation of forests and the exploitation of underground mineral resources. Lead to a large amount of soil and water loss, frequent geological disasters, landslides are not uncommon. The number of landslide disasters that occur every year is countless, causing great harm to human life and property, seriously affecting the progress of human society, and restricting the country's economic development. Although the research on the mechanism of landslide disasters, the prevention and control technology a...
