Description
Technical Field

Background
Slope protection is one of important subjects of geotechnical engineering research, and slope stability is improved by adopting surface water protection, slope surface reinforcement protection and other modes for a slope. Because the expansive soil has the characteristics of easy weathering and easy expansion, contraction and deformation, the side slope instability is more common and serious compared with other soil qualities. Therefore, when the slope containing the expansive soil layer is protected, the slope surface is reinforced and protected particularly. At present, vegetation protection, fully-closed slope protection and the like are generally adopted for reinforcing the slope surface of the expansive soil slope.
The vegetation protection is to lay a layer of three-dimensional net mat on the slope, and the kinetic energy of rainwater and slope water flow is decomposed or reduced through the net silking of the three-dimensional net mat, so that the rainwater erosion is relieved, and the soil is protected. Meanwhile, the vegetation plays a role in greening the side slope, and the stability and the soil erosion resistance of the side slope are improved. However, when the water quantity passing through the slope surface is large, the protection effect of vegetation protection on the water body permeating into the lower soil is limited, so that the swelling soil absorbs water and swells to easily cause the instability of the slope. Meanwhile, the work load of artificial slope vegetation maintenance is increased by vegetation protection, and the slope maintenance cost is increased.
The totally-enclosed slope protection means that concrete or grouted rubble is used for forming a closed frame type structure on the slope surface of the slope to prevent the slope from being unstable. However, compare in other soil property, when this mode was applied to the protection of inflation soil side slope, because inflation soil's breathing sensitivity is higher, therefore the water proof of concrete inoxidizing coating, thermal-insulated effect can be relatively poor, can make the humidity of surface soil change, and then lead to domatic surface soil to take place the breathing deformation, influence the protective effect on whole domatic.
