Problems solved by technology

The method itself has high precision, but it is difficult to make highly accurate evaluation and early warning due to the influence of geological model, simplified mechanical model and mechanical parameters
[0004] Therefore, in most cases, the prediction results of the above-mentioned early warning methods are still not ideal.

Embodiment

[0165] In order to further illustrate the implementation process of this patent, a certain rock mass slope is taken as an example to describe in detail.

[0166] The unstable rock mass (limestone) slope is located on the left bank of a hydropower station near the dam reservoir. Under the influence of structural damage, unloading, weathering and heavy rain, the mountain body forms two unstable rock mass areas, the large and the small. The rock mass separated by a large fissure on the surface is the object of calculation in this example.

[0167] Step 1: Preliminary survey of landslide and layout of displacement monitoring points

[0168] Carry out preliminary investigation and mapping of the landslide to be evaluated, find out the structural plane or large crack that has a great impact on the stability of the rock mass slope, arrange and install the fiber grating sensor at this position, and cooperate with a data remote transmission DTU device launched by a domestic manufactur...

Abstract

The invention relates to a method for monitoring and alarming rock landslide by using a tide generating force and belongs to the field of rock landslide stability evaluation and prevention. The methodmainly comprises the following steps: (1) performing primary reconnaissance on landslide, and allocating displacement monitoring points; (2) confirming a theoretic strain value of earth tide acting on a slope rock mass; (3) confirming a loading and unloading monitoring period of the earth tide to a landslide rock mass; (4) confirming a loading and unloading displacement influence rate of the earth tide to the landslide rock mass; (5) confirming loading and unloading displacement response of slope earth tide; (6) confirming slope loading and unloading displacement response ratio stability criterion rules, and performing stability evaluation. The method has the beneficial effects that on the basis of loading and unloading response ratios and earth tide theories, landslide preparation mechanisms and landslide displacement monitoring data are organically integrated, the tide generating force of the sun and the moon to the earth for periodical change is adopted as loading and unloading means, and novel displacement power coupling prediction forecasting methods are established in sequence.

Description

technical field [0001] The invention relates to a method for monitoring and early warning of rock landslides by utilizing tidal force, which belongs to the field of stability evaluation and prevention of rock landslides. Background technique [0002] In recent years, landslides have become the most frequently occurring geological disaster among geological disasters, which are shocking both in terms of frequency of occurrence and consequences. Especially for rocky slopes, there are often no obvious external signs of damage, so the suddenness of landslides is also the main cause of serious disasters. In order to minimize the losses caused by landslide disasters, we need to predict the time when geological disasters may occur and the spatial range of possible instability and damage. [0003] Experts and scholars at home and abroad have made many achievements in the research on the mechanism and prediction methods of landslides, and have also proposed many effective models and ...
