The present invention discloses a method for setting the height of the upper and lower structures of a two-stage stepless reinforced earth structure, comprising: (1) determining the total reinforcement tension required for the upper and lower structures, and calculating the maximum reinforcement tension required for each layer; (2) calculating the reinforcement length and reinforcement area required for each layer of the upper and lower structures, thereby determining the reinforcement and filler usage; (3) calculating the carbon emissions of the reinforcement and filler, and ultimately determining the total carbon emissions; (4) repeating steps (1-3), from the upper structure being one layer until the total carbon emissions when the total reinforcement tension required for the lower structure is zero are calculated, comparing and determining the minimum total carbon emissions, and the corresponding upper and lower structure height is the optimal structural height setting. Based on the principle of minimizing the total carbon emissions generated by the required reinforcement and filler, the present invention solves the uncertainty problem of the upper and lower structure height setting while ensuring the safe design of the two-stage stepless reinforced earth structure, thereby providing a more environmentally friendly design solution.

This invention provides a sustainable and environmentally friendly consolidating material that can be supplied stably and does not cause environmental problems such as environmental pollution or increased carbon dioxide emissions, thereby enabling not only carbon neutrality but also carbon negativity, as well as a method for constructing soil structures and a ground improvement method using this material. [Solution] This solidifying material is mainly composed of silica-containing combustion products, which are obtained by partially burning and cooling land-derived waste and contain SiO2 and carbon as active ingredients. The amorphous silica in the silica-containing combustion products undergoes a hydration reaction and solidifies, thereby enabling carbon negativity.

The present invention discloses a variable stiffness permeable anchor, reinforcement method, and structure suitable for raw earth structure ruins, comprising a permeable anchor section and a variable stiffness anchor section arranged in the soil of the ruins; the permeable anchor section is configured with a perforated bamboo tube inserted into the anchor, and the area between the perforated bamboo tube and the soil of the ruins is filled with water-absorbing material to form a water-absorbing section; the variable stiffness anchor section is configured with a bamboo tube with anchor blockers arranged at intervals, and the anchor reinforcement inserted into the bamboo tube is spaced apart with positioners to form a variable stiffness cavity; the tails of the anchor reinforcements in the two sections are connected to a steel wedge, and the fronts extend out of the soil of the ruins for fixation; the bamboo tubes are isolated from each other; and the anchor blockers are rotated along the bamboo tube by tension on the anchor reinforcement, thereby achieving variable stiffness. This structure has both permeable and variable stiffness functions, which can ensure that the anchor system still maintains a high pull-out bearing capacity when the interface slip is large, and can also ensure that the moisture content of the surrounding soil is at a low level through permeable drainage.
