摘要:
A method for constructing a mechanically stabilized earthen embankment has the steps of constructing a wall facing element, and determining a plane of maximum force and a zone of maximum force in the earthen embankment to be formed. A plurality of elongate soil reinforcement elements are bent to form semi-extensible bent segments, but such that proximal and distal portions remain substantially straight and inextensible. The elongate soil reinforcement elements are positioned such that the semi-extensible region is within the zone of maximum force, and the proximal ends are connected to the wall facing element. Fill soil is added to build the earthen embankment, and the process is repeated until the earthen embankment is formed.

A soil reinforced retaining wall includes a soil reinforcing mat connected to a face panel. The face panel is vertically disposed with a back facing the earthen formation and is preformed to include an anchor embedded in the face panel and extending from the back in at least one predetermined location. The soil reinforcing mats are horizontally disposed within the earthen formation in general correspondence with the predetermined location. The mats have an end adjacent the face panel folded to form substantially a right angle portion of the mat including a vertical face and a horizontal face. A right angle member having a vertical face and a horizontal face is disposed in contact with the corresponding vertical face and horizontal face of the right angle portion of the mat. The right angle member is then secured to the anchor such that the right angle portion of the mat is rigidly held therebetween.

Connectors are provided for securing soil reinforcing elements to the face panels of a retaining wall for an earthen formation. The connectors comprise rigid eyes fixed to the panels and extensions formed on the elements for extension through the eyes. The eyes and extensions are selectively locked together and serve to orient the reinforcing elements in a horizontal disposition within the soil embankment being reinforced.

Low-cost and very effective retaining walls are constructed with stacked, generally rectangular, trays of steel wire fabric sheets, each with one end bent up to form a portion of the wall face. In constructing a wall, a first course of trays is set in place and filled, with filtering rocks and/or mats being placed toward the front and against the bent-up face section and fill soil being placed to the rear of the tray. A second course of trays is then placed on top of the first course and the corner of the face bend of the second course is securely fastened to the top of the lower course. Thus, the top of each face is supported and each course is anchored by the next course, thereby resulting in a strong monolithic and permeable wall that will readily conform to irregularities and settling of the foundation surface.

A soil reinforced retaining wall for an earthen formation is provided by embedding planar soil reinforcing mats in the formation at vertically spaced intervals and securing face mats between the soil reinforcing mats. The face mats include fingers extending distally from the edges thereof for engagement with opposite sides of a complimental face mat, whereby the mats are held in general vertical alignment. Certain of the fingers are of a gently curved configuration to frictionally hold edge portions of the face mats in spaced relationship for compression toward one another to accommodate settlement of the earthen formation, without bulging of the face mats. An L-shaped starter mat is engaged within a recess formed at the foot of the formation to provide an upstanding portion engaged with the lowermost is face mat to hold the mat in a generally vertical orientation. A tail is provided on the uppermost face mat for embedment within the backfill to cap the wall.

A retaining wall for an earthen formation uses welded wire face mats having upright portions secured to one another and spanning the distance between successive lifts of the wall at the face of the formation. Elongate welded wire soil reinforcing mats with bent-up ends of a height less than the distance between successive lifts are secured to the face mats so as to extend partially over the upright portions and into the earthen formation. The bent-up ends of the soil reinforcing mats are formed with kinks which extend through the upright portions of the face mats. Rods extend through these kinks to secure the upright portions of the face mats against separation from the bent-up ends of the soil reinforcing mats. In a preferred embodiment, the face mats have a width greater than the width of the soil reinforcing mats and the soil reinforcing mats at each lift of the wall are spaced from one another and span adjacent face mats.

A retaining system for an earthen formation is disclosed. The earthen formation is reinforced against slippage by embedding an array of anchor members within the formation. The face of the formation is defined by a plurality of the elongated panels stacked in a vertical arrangement. The anchor members are secured to the panels via a support bar. The support bar includes an array of holes through which the ends of the anchor members are received and upset to define a rivet head. The support bars are engaged between the upper and lower edges of the face panels to provide support and maintain vertical alignment of the face panels.

A first embodiment employs precast cementitious stretchers provided with cast in place connectors for anchor rod ends. A second embodiment employs stretcher panels fabricated of resilient sheet material and secured together by straps which reinforce to panels and provide connectors for anchor rod ends. Both embodiments incorporate deadman anchors formed with slot-like openings through which end plates on the rods may pass and which serve to secure the plates against removal from anchors when the rods are secured to the connectors of the stretchers.
