Technical Field
The invention relates to the technical field of loess slope ecological protection methods, in particular to a loess slope ecological protection method.
Background
Landslide and slumping are the main modes of sand production by neutral erosion in loess. The yellow river silt is input into the loess plateau for 16t each year, so that the lower reaches of the yellow river become a famous ground hanging river. In addition, the landslide also provides a large amount of material sources for the occurrence of debris flow which is another natural disaster in the mountainous area. Therefore, it is important to fully recognize the characteristics of the loess slope and perform stability analysis on the loess slope.
Loess is a quaternary sediment, develops a vertical joint and has strong structurality; the reinforcing cohesion of the cementitious substance is a major component of its strength. Under the influence of drought, loess slopes with low natural water content, high strength and high steepness are very common. Due to the poor water resistance of the cementitious material between the loess particles. The increase of the water content of the land weakens the effect of strengthening cohesion, and the strength of the loess is reduced, and even a plurality of engineering damages occur. Loess valley highland limit topography is precipitous, and is more than 30, and valley depth of cut is often tens meters, and the slope foot of loess valley is because of being corroded by the rivers in addition, and the bank forms scarp slope, poor stability. These properties of loess lithology and topography determine the characteristics of the loess slope: firstly, the method comprises the following steps: the manually excavated side slope is high and steep, the vegetation condition is poor, the side slope is often severely washed by rainwater, and the waistcoat is influenced by rainwater infiltration; II, secondly: under the washing of surface runoff, the loess slope is mostly provided with gullies, caves and the like; thirdly, the method comprises the following steps: cracks in the soil layer develop, so that the integral strength of the loess side slope is poor; fourthly, the method comprises the following steps: the loess slope is easy to peel off along with the change of natural conditions; fifthly: the loess landslide has large scale and kinetic energy, strong destructive power and heavy disaster loss.
