An optimal design method and system for slope reinforcement with anti-slide piles includes: modeling a slope type to obtain a three-dimensional (3D) slope numerical calculation model; establishing different numerical calculation models for anti-slide piles according to different reinforcement schemes of the anti-slide piles; determining optimization indexes through a coupling analysis of the 3D slope numerical calculation model and the anti-slide pile numerical calculation model; calculating a comprehensive optimization value according to the optimization index; determining an optimal anti-slide pile reinforcement scheme according to the comprehensive optimization value, and determining whether the optimal anti-slide pile reinforcement scheme meets the optimization objective; and carrying out slope reinforcement according to the optimal anti-slide pile reinforcement scheme if yes. A multi-objective comprehensive optimization model including an optimization index system and comprehensive weights of optimization indexes is established.

An articulating mattress of blocks interconnected with tensiles seated therein, said blocks having opposing longitudinal and transverse sides and a top surface each of a smooth surface by contact with a mold surface during casting and a bottom surface having a rough surface by screeding the flowable casting material from an open side of a mold formwork. The mattress inverted with a rolling apparatus for installation with the rough surface in frictional contact on a ground surface for erosion control, said mattress rolling apparatus having base, front wheels, and steerable rear wheels, with a rolling mechanism for rolling the articulating mattress. An apparatus and a method of casting an articulable mattress with a rough bottom surface for erosion control are disclosed.

The present invention is directed to a horizontally extendable silt fence. The present invention is also directed to a silt fence system comprising a horizontally extendable silt fence comprising a water permeable geotextile material having an upper edge and a lower edge, and a plurality of posts comprising an upper portion strutted and arranged to be coupled with the upper edge of the water permeable geotextile material, a lower portion structured and arranged to be coupled with the lower edge of the water permeable geotextile material, and an anchor portion structured and arranged to be driven into the ground to anchor the post. Also disclosed is a method of filtering silt from a fluid stream.

A system for centering a reinforcing member within a drilled shaft/bore hole includes a first cage member and a second cage member. The first cage member is operable to surround a first half of the reinforcing member. The second cage member is operable to surround a second half of the reinforcing member. The second cage member is operably connected to the first cage member, and the first and second cage members have identical shapes.

A soil retaining system combining flat sheet pile walls in an open cell configuration includes integral soil anchors providing an improved earth retaining system. Another aspect of the invention is a method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the improved earth retaining system.

Disclosed is a full-section anti-slide water-cut wall for treating giant landslides, which comprises at least one water-cut wall embedded in the landslide and arranged along the direction of blocking the movement of a sliding body; the water-cut wall comprises a plurality of anti-slide piles arranged at intervals, the bottom end of the anti-slide piles extend into the sliding bed, and a blocking wall is fixedly connected between adjacent anti-slide piles; the anti-slide pile and the blocking wall are provided with a plurality of drainage holes.
