Embodiment 1

[0047] This example takes the Rumei Hydropower Station as an example. The Rumei Hydropower Station is located in the upper reaches of the Lancang River in the Tibet region of my country. The hard rock in the dam site area cuts deep into the valley, and the middle and upper parts of the high and steep bank slope and the shallow rock mass are affected by continuous stress release. It shows a strong relaxation phenomenon, coupled with the unique climatic conditions of the alpine valley, forming a broken loose rock mass and an unloaded rock mass. ) deformation and stability features become the focus of engineering attention. The safety of the fractured and loose rock mass slopes widely distributed in the dam site area and even the hub area of ​​Rumei Hydropower Station has become an important factor restricting the success of the project. Traditional methods are no longer suitable for the safety monitoring and management of such large-scale fractured rock mass slopes during the cons...

Abstract

The invention relates to a side slope full-life-cycle safety management method based on digital mapping. The method comprises the following steps: constructing a mapping side slope based on terrain and geological information; correcting the constructed mapping slope based on monitoring, detection and detection information coupling mutual feedback; and based on a method library, a knowledge base and an evaluation model information, carrying out slope full-life-cycle safety management in combination with the corrected model. According to the invention, a comprehensive operation management 'mapping side slope' digital model with comprehensive real-time online perception, data fusion and sharing, rapid analysis and diagnosis and intelligent operation decision is built through a 'digital mapping' technology; therefore, the intelligent management and control level of slope safety is improved, the construction and operation period emergency treatment of slope engineering are guided, the fulllife cycle safety of the slope is ensured, the safety management of the full life cycle of the slope is promoted, and the development of the industry technology is promoted.

Description

technical field [0001] The invention relates to a method for safety management of the whole life cycle of a slope, in particular to a method for safety management of a whole life cycle of a slope based on digital mapping. Background technique [0002] A number of large-scale hydropower projects will be built in the Qinghai-Tibet Plateau region of my country. Due to complex plate tectonics and sedimentation, internal and external dynamic geology, and harsh natural conditions, large-scale accumulation landslide groups and widely distributed fragmented loose rock mass edges have been formed. slope. These unfavorable geological bodies are in a critically stable or basically stable state under natural conditions, but under long-term operating conditions such as construction disturbance or heavy rain, earthquake, water storage, and water level alternation, the evolution law of slope stability is complicated, and the traditional limit equilibrium method is adopted It is difficult to...
