Definitions

  • the present invention relates to stabilization system; and more particularly an interlocking stabilization system for stabilizing slope, unrestrained earth or the like.
  • slope stabilization which normally involve extensive grading are slope alteration and complete removal of a hazard.
  • the slope alteration usually includes variations of cuts and fills technique.
  • the most common technique used to stabilize slopes is a buttress fill. Accordingly, buttress fills are usually used to stabilize poorly consolidated or incompetent bedrock, and for the relatively weak sedimentary formations.
  • a typical compacted fill buttress is constructed by removing the outer face of a cut slope and replacing it with engineered, compacted fill.
  • buttress fill mass is designed specifically to retain the slope behind it, usually with a safety factor of at least 1.5.
  • Buttress fill slopes are generally constructed with a finished grade of 2:1 (horizontal to vertical); however, steeper gradients are sometimes acceptable if sufficient shear strength of the resultant fill slope is attained.
  • Stabilization fills are similar to buttress fills, except the fill mass is not designed to support surfaces of weakness or deep seated landslides. Rather, the fill is constructed along a slope face to mitigate surficial slope failures, such as ravelling, erosion and rock falls.
  • the base width of stabilization fills is commonly half the height of the slope.
  • Another stage in stabilizing a slope is to establish control of surface and groundwater systems. Accordingly, water control is generally maintained through installation of surface and subsurface drainage devices within and adjacent to potentially unstable slopes.
  • Surface and subsurface drainage design usually include consideration of the effects of surface runoff and groundwater migration on the stability and water quality of adjacent sites.
  • the control of surface and groundwater flow is important in minimizing erosion and siltation both on and off site.
  • a proper designed in drainage system should increase slope stability and decrease erosion and siltation.
  • ground inclusion is a metal bar that is driven or drilled into competent bedrock to provide stable foundation for structures such as retaining walls and piles, or to hold together highly fractured or jointed rock. Ground inclusions can be used at times as alternatives to the foundation piles which are typically used to support structures within mountainous or steep areas.
  • ground anchors soil nails and rock bolts.
  • Permanent ground anchors are tendons which are placed in competent rock or soil to control displacements and provide vertical and lateral support for engineered structures and natural slopes. Anchors are normally used in waterfront structures and to tie-back retaining walls to prevent failures due to rotational loading or failures due to buoyant forces of water.
  • Soil nailing is a soil reinforcement technique that places closely spaced metal bars or rods into soil to increase the strength of the soil mass. Accordingly, soil nails can be either installed in drilled bore holes secured with grout, or they are driven into the ground. The soil nails are generally attached to concrete facing located at the surface of the structure. The function of the facing is to prevent erosion of the surface material surrounding the soil nails, rather than provide structural support. This facing can be constructed to mimic the look of the surrounding landform and provide spaces for vegetation; however, the facing will not be the same as the existing top soil.
  • Rock bolting is a method of securing or strengthening closely jointed or highly fissured rocks in cut slopes by inserting and firmly anchoring a steel bar in predrilled holes in a suitable length.
  • Rock bolts generally have heads that expand following installation and are classified according to their method of anchorage: expansion, wedge, grouted and explosive. Like soil nails, these bolts generally are attached to some type of facing.
  • ground inclusions Limitations and considerations for the use of ground inclusions are usually in the area of long term stability. Metal inclusions are generally protected from corrosion by a sealant or grout; however, in environments where there is frequent interaction with groundwater, breakdown of inclusions is accelerated. Also, the effects of creep on the structural integrity of a wall or other anchored systems must be considered in the design of a structure. Moreover, there are specific soil liquidity and plasticity limits that are not suitable for the use of anchors. The anchors may however be limited, and excavation would undermine the stability of any anchors present.
  • piles are long, relatively slender columns positioned vertically in the ground or at an angle (battered) used to transfer load to a more stable substratum.
  • Piles are often used to support or stabilize structures built in geologically unstable areas. The effectiveness of piles is increased dramatically when they are incorporated into an anchored stabilization system.
  • piles are used to minimize the effects of scour and undercutting along the foundations of waterfront structures.
  • piles are either driven into the ground or they are placed in drilled holes. Piles placed in drilled holes directly support the weight of a structure. Driven piles are installed in soft or loosely consolidated material and often do not directly absorb the load of a structure.
  • the retaining walls are engineered structures constructed to resist lateral forces imposed by soil movement and water pressure. Although grading is necessary for construction of all retaining walls, the excavation takes place predominantly along the toe of a slope, with the upper slopes requiring little if there be any alteration. Since cutting the toe of a slope can destabilize the slide, the construction of retaining walls at the toe of a slide should be undertaken only after it has been determined that the slide can remain stable during construction. Retaining walls are commonly used in combination with fill slopes to reduce the extent of a slope to allow a road to be widened and to create additional space around buildings.
  • Retaining walls are also used as protection against the erosive forces of water and as a method of slope stabilization along highways, railroads, and construction sites. Retaining walls are also used along the coast for protection against wave damage and bluff failure. Both vertical walls and revetments can be used for protection, and the design for each must consider beach scour, storm wave height, wave run-up, tide level and future sea level conditions, as well as the geologic properties of the bluff face. Retaining walls can be separated into categories based upon the force parameters acting on the structure to provide stability. The three types of retaining walls are anchored, gravity, and cantilever. All three can be used as coastal structures and for slope stabilization.
  • U.S. Pat. No. 6,796,745 B2 discloses a soil nailing system, wherein the system generally includes a temporary retaining wall for an excavation sidewall. Soil nails extend outwardly into the soil sidewall and are integrated with the temporary retaining wall.
