Description

Branch structure is administered to river-adjacent large-scale landslide of collecting reservoir bank renovation as an organic whole
Technical Field
The utility model relates to a landslide is administered and reservoir bank renovation engineering technical field, and more specifically it is that it is a large-scale landslide in river who collects reservoir bank renovation and administers a shelves structure as an organic whole.
Background
The geological disaster risk is increasingly prominent, the life safety of people is seriously harmed, and the development of cities and towns in a reservoir area is restricted; taking the three gorges reservoir area as an example, after the three gorges project is constructed, the reservoir water storage forms a reservoir bank with the length of about 5300 kilometers, and the landslide found at present reaches over 5000 places.
For the large landslide close to the river, along with the change of the water level of the river, under the common influence of factors such as the action of reservoir water power, the activities of human beings at the upper part, rainfall infiltration and the like of the landslide in the range of a water falling area close to the river, the shear strength of rock and soil bodies of the landslide body is reduced, the stability is deteriorated, the risk of landslide sliding is increased rapidly, and further the safety of residents and facilities close to the river and the normal navigation of a Yangtze river channel are threatened, so that the effective management of the large landslide close to the river is in the forefront.
The geological conditions of the reservoir area are generally dangerous, and the large landslide close to the river generally has the characteristics of large volume, thick covering layer, steep soil-rock interface, poor stability, large gliding thrust, large harm and the like. The landslide is large in volume and thousands of squares, the coverage thickness is tens of meters deep, the stability of the landslide is greatly influenced by periodic water level lowering and rising, and most landslide bodies are in an under-stable state.
Common landslide control methods include: load reduction, presser foot, drainage, landslide body clearing, support rail clearing and the like.
For a large landslide close to the river, a single drainage measure has little effect on the stability of the landslide. The load reduction and the landslide mass clearing are seemingly simple and effective, but the excavation amount of the hydro-fluctuation belt of the reservoir area is large, the influence on the ecological environment and the landscape environment of the hydro-fluctuation belt close to the river is large, and the construction of the landscape along the river in the reservoir area is not facilitated. The pressure foot measures are generally large in the aspect of large landslide, and the effective storage capacity of the reservoir is easily invaded and consumed. Therefore, the treatment of the large landslide close to the river does not suggest to adopt load shedding and landslide mass clearing.

The anti-slide pile has the advantages of strong applicability, stability to landslide, small interference to geological environment and the like, and is mainly suitable for shallow layer and medium-thick layer rock landslides, medium-thick layer soil landslides, and rock and soil landslides buried with a plurality of layers of weak interlayers. However, large landslide close to river has abundant underground water, large-section manual hole digging slide-resistant piles are difficult to adopt, the common maximum pile diameter of a mechanically-formed cast-in-place pile is about 2.5m, and compared with soil landslide with tens of millions of grades and thousands of kilonewtons of residual gliding thrust, the treatment effect of the single-row slide-resistant pile is difficult to guarantee due to the limited rigidity of the pile body of the single-row slide-resistant pile; if the grade is simply graded, the grade effect is difficult to be fully exerted and ensured.
