Embodiment 1

[0034] like figure 1 Shown, a kind of early warning method of monomer pipeline landslide disaster, comprises the following steps:

[0035] a. Investigate the development characteristics of landslide disasters, carry out field surveys of pipeline landslide disasters, and conduct surveys and mapping of pipeline landslide disasters. The content of survey and mapping includes: landslide range, scale, topographical conditions, deformation characteristics, geological conditions, and the positional relationship with pipelines, etc.; According to the results of landslide disaster survey and mapping, the layout design of automatic monitoring stations is carried out, which mainly includes: ① Install automatic monitoring devices for pipeline landslide deformation to monitor the deep displacement and surface displacement of landslide deformation at the place with the largest potential deformation in the landslide area, such as Figure 3-a , Figure 3-b ②The pipeline strain automatic moni...

Abstract

The invention discloses an early warning method for landslide disasters of a single pipeline, and relates to the technical field of early warning of landslide disasters of pipelines. The method comprises the following steps: monitoring landslide deformation data (landslide surface displacement B and deep displacement S), rainfall data (rain intensity I and duration T) and pipeline strain data (pipeline strain value epsilon) of the single pipeline, and constructing a three-dimensional early warning matrix model based on a ground disaster deformation index X, an external induction index Y and amechanical index Z of the pipeline, so that early warning of landslide disaster risks of the single pipeline is realized. The early warning method for landslide disasters of the single pipeline breaksthrough the traditional early warning technical method of manually setting a single index, comprehensively considers the influences of disaster body deformation (ground disaster deformation), receptors (pipeline stress) and external inducing factors (rainfall), enables early warning results to be more practical, and greatly improves the early warning precision of landslide disasters of pipelines.

Description

technical field [0001] The invention relates to the technical field of early warning of pipeline landslide disasters, in particular to a method for early warning of single pipeline landslide disasters. Background technique [0002] Landslide refers to the overall slide caused by shearing along a certain weak surface (or weak zone) inside the slope under certain natural conditions and geological conditions. Destruction, individual pipeline landslide disasters refer to landslide disasters that cause harm to the safety of the pipeline transportation system and the operating environment. Landslide disasters are very harmful to the passing pipelines, often resulting in extrusion and deformation of the pipelines, leakage of the conveying medium, pollution of the surrounding environment, and even explosions in serious cases, affecting the lives and property safety of the surrounding people. [0003] For landslide disasters, the deformation of landslides can usually be monitored by...
