Embodiment 1

[0044] The method for prevention and control of light soil landslide geological disaster of the present embodiment comprises the following steps:

[0045] 1) Topographic survey

[0046] Carry out topographic survey, investigation and analysis of the landslide geological area to be treated, determine the potential landslide area, determine the size and boundary of the potential landslide body. The landslide body in this embodiment is a layered loess structure with a downward slope, and the inclination angle of the layer is about 25°. The thickness of the landslide body (the thickness from the surface of the landslide body to the sliding surface) is about 10m on average.

[0047] 2) Slope cutting treatment

[0048] The potential landslide body determined in step 1) is subjected to slope cutting processing. During slope cutting processing, the slope body at the upper end of the potential landslide body, which accounts for about one-third of the height of the landslide body, is ...

Embodiment 2

[0054] The method for prevention and control of light soil landslide geological disaster of the present embodiment comprises the following steps:

[0055] 1) Topographic survey

[0056] Carry out topographic survey, survey and analysis of the landslide geological area to be treated, determine the area where the landslide occurs, and determine the size and boundary of the landslide body. The landslide body in this embodiment is a layered structure of loess with a downward slope, and the inclination angle of the layer is about 20°. The thickness of the landslide body (the thickness from the surface of the landslide body to the sliding surface) is about 15m on average.

[0057] 2) Slope cutting treatment

[0058] The landslide body determined in step 1) is carried out slope cutting processing, and during slope cutting processing, the slope body that the upper end of the landslide body accounts for about 1 / 3rd of the height of the landslide body is removed to the sliding surface...

Abstract

The application discloses a light weight soil landslide geological disaster prevention and control method, and belongs to the technical field of environmental treatment. The light weight soil landslide geological disaster prevention and control method comprises the steps of: cutting a slope of a landslide body; and backfilling artificial soil on a slope surface after slope cutting to form a backfilled slope surface. The artificial soil is prepared from the components in parts by weight: 30-50 parts of raw soil, 15-25 parts of cement, 30-45 parts of fly ash, 10-15 parts of polymer microspheres,5-8 parts of latex powder and 10-18 parts of heavy calcium powder. According to the light weight soil landslide geological disaster prevention and control method, the method of cutting the slope of the landslide body and then backfilling the artificial soil is adopted, original unstable soil mass is cleared, the hidden danger is removed, and the stability of the slope body is ensured by using backfilled light artificial soil with uniform texture.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, and more specifically, relates to a method for preventing and controlling geological disasters of light soil landslides. Background technique [0002] Landslides are common geological disasters, which generally refer to the geological phenomenon in which the mountain body slides down the sliding bed under the influence of rainwater immersion, river scouring, engineering construction and other factors. Due to the high energy carried by the sliding body during landslides, the damage it causes is also very large. In severe cases, houses will be buried and casualties will be caused. [0003] Landslides usually occur in the presence of certain incentives, such as landslides caused by continuous rainstorms in southern my country. In order to avoid or reduce the harm caused by landslides, it is generally necessary to control and transform the geological environment before landslides occ...
