Description
Technical Field
The utility model belongs to the technical field of the geotechnical material, concretely relates to core suction adds muscle geotextile.
Background
Reinforced geotextiles, including woven geotextiles, knitted geotextiles, and composite geotextiles, are commonly used for soil reinforcement to improve the mechanical stability of soil. The reinforced earth structure can be called as a mechanical stabilized earth structure and comprises a reinforced abrupt slope, a reinforced retaining wall, a reinforced embankment side slope, embankment foundation reinforcement on soft soil, a pile-supported reinforced embankment, a hollow reinforced embankment embedded with the hollow ground, a reinforced earth sealing layer covered on a landfill site, a reinforced embankment bed layer on the embankment and a reinforced embankment bed on the soft soil.
A typical structure of a soil reinforced geotextile for reinforcing a side slope in the prior art is shown in fig. 1, wherein the soil comprises foundation soil 11 and backfill 12, the side slope formed by the backfill 12 is horizontally reinforced by using a primary reinforcement material 13 and a secondary reinforcement material 14, the primary reinforcement material 13 is generally used for a steep slope section with a high reinforcement requirement, the secondary reinforcement material 14 is generally used between the primary reinforcement materials 13 of the steep slope to reduce the expansion of the slope, and the secondary reinforcement material 14 is also used for a gentle slope section with a medium reinforcement requirement. The slope surface of the steep slope section is also provided with a soil bag 15 for blocking back filling soil 12 and forming a stable steep slope surface.
The effect of the reinforced geotextile on the mechanical stability of the soil is determined by the mechanical properties of the reinforced geotextile, particularly the tensile strength at 5% elongation and the creep resistance in the service life. The reinforced geotextile can be produced using a high tenacity polyester yarn, a high tenacity polypropylene yarn or a combination of high tenacity polyester and high tenacity polypropylene yarns, which can be used in the machine direction or cross direction perpendicular to the machine direction of the fabric. The high-toughness polyester has high tensile strength and high tensile modulus, has excellent creep resistance and environmental degradation resistance in the service life of up to 120 years in a soil environment, can be used as a base material for manufacturing a main soil reinforcement material with long-term effect, and provides high tensile strength in an area needing soil movement resistance. The high tenacity polyester yarns may be used in the machine direction of the reinforced geotextile, which is the same as the main soil strain direction. The high-toughness polypropylene has medium tensile strength and medium tensile modulus, has strong creep resistance and excellent environmental degradation resistance in the service life of up to 120 years in the soil environment, can be used as a base material for manufacturing a long-acting secondary soil reinforcement material, and provides medium tensile strength in a soil movement resistant area. High tenacity polypropylene yarns may be used in the machine direction of the reinforced geotextile, which is in line with the main soil strain direction.
The long-acting soil reinforced geotextile in the prior art generally has high modulus property and long-term creep resistance, but the reinforced soil has poor stability under rainfall, particularly under the condition of continuous rainfall. During continuous rainfall, it is common to see an increased incidence of damage to soil structures such as earth slopes, embankments, road structures, topsoil layers of landfills, which are common in soil structures where existing soil reinforcement is not used or is used.
In the rainfall process, part of rainwater flows away from the earth surface, part of rainwater permeates into the ground, the water content of soil in the permeation influence area is increased, in the continuous rainfall process, the soil permeation influence area is widened and deepened, and a soil saturation zone is formed in the permeation influence area. In addition, soil capillary action can absorb the moisture of ground water level, increases the moisture content of soil in the capillary rise influence zone, and in the rainfall process that lasts, ground water level rises, and capillary rise influence zone will upwards expand. On a sloping field, the underground water level is inclined, the groundwater flows from high to low due to different diving positions, and under the condition of continuous rainfall, the seepage flow is increased, so that the water content of soil in a seepage influence area is increased. Thus, during sustained rainfall, the water content of the surface soil generally increases, the degree of increase in water content and the degree of soil saturation will depend on the intensity and duration of the rainfall, and the increase in soil water content and soil saturation will increase the water pressure, decreasing the soil intensity. Muawiaa. Dafalla (Dafalla m.a. effects of clay and soil content on direct samples for clay-binders [ J ]. Advances in Materials Science and Engineering,2013) investigated the effect of soil moisture content on the internal friction angle and cohesion of soil, which is formed by mixing swelling clay with sand, at 5%, 10% and 15% proportions, respectively, and the tests showed that the internal friction angle and cohesion of soil decrease with increasing soil moisture content.
In addition, in the soil reinforcement structure, the backfill soil increasingly adopts barren soil with high fine grain content, the fine grain soil generally forms a soft foundation, the fine grain soil essentially has the mechanical property of being sensitive to moisture, and the shear strength of the fine grain soil is reduced along with the increase of the water content of the soil.
One conceptual slip failure of a reinforced soil structure is shown in fig. 2. The soil includes foundation soil 21 and backfill 22, and the side slope of the backfill 22 is horizontally reinforced by a reinforced geotextile 23. The slip damage includes soil shear damage 24, reinforced geotextile 23 mechanical fracture shear damage 25, and interface shear damage 26 between the reinforced geotextile 23 and the soil, and also includes damage 27 of pulling out the reinforced geotextile 23 from the backfill soil 22. Therefore, any improvement that increases the shear strength of the soil, increases the shear strength of the interface between the geotextile and the soil, and increases the pull-out resistance of the geotextile from the soil will further increase the stability of the reinforced earth structure.
The prior art generally provides more slip-resistant destructive power by additionally improving the mechanical strength of the reinforced geotextile, thereby increasing the stability of the soil. However, this method is expensive, and since the soil is difficult to absorb and discharge water during rainfall, the improvement of the soil in the ability to resist sliding damage is limited.
The geotextile with the water absorption function is expected to improve the anti-slippage destruction capability of the soil. The existing research shows that the fiber with the special-shaped cross section has a wicking function, and the geotextile with the water absorbing and draining functions can be prepared by adopting the fiber with the special-shaped cross section. Figure 3(a) shows a circular cross-section yarn 31 and figure 3(b) shows a tri-lobal cross-section yarn 32 with micro-channels, comparing that the tri-lobal cross-section yarn 32 wicks moisture 33 more strongly than the circular cross-section yarn 31. Fig. 4 is a graph comparing the rise in capillary water absorption under the same test conditions for the tri-lobal polyester yarn, the natural round polyester yarn and the fibrillated polypropylene yarn, and it is apparent that the tri-lobal polyester yarn has enhanced water absorption properties.
