Embodiment
[0028] Embodiment: a design method for non-uniform laying of reinforced bodies in reinforced soil structures, such as figure 1 , figure 2 and image 3 shown, including the following steps:
[0029] 1) To determine the strength of the reinforced body in the reinforced soil structure, use the limit equilibrium method to search for the most dangerous failure surface T in the reinforced soil structure, and use the calculation formula:
[0030]
[0031]
[0032]
[0033]
[0034]
[0035] Calculate the strength of the reinforced body required for multiple trials, and select the largest strength T of the reinforced body required in the trial calculation process max As the strength of the reinforced body in the reinforced soil structure, M is the sliding moment of the potential sliding surface of the reinforced soil relative to the rotation center, n is the number of layers of reinforcement, and r 0 is the distance from the rotation center O of the failure surface ...

The invention discloses a design method for non-uniform laying of reinforced bodies in a reinforced soil structure, relates to the technical field of geotechnical engineering, and solves the problem that a reinforced body of uniform length cannot be laid at the rear of a reinforced soil structure due to space constraints Problem, the main points of its technical scheme are: comprise the following steps: 1) determine the strength of the reinforced body in the reinforced soil structure; 2) determine the laying length of the topmost reinforced body in the reinforced soil structure; 3) repeat steps 1) and In step 2), the length of the reinforced body of each layer of the failure surface in the reinforced soil structure is calculated sequentially from top to bottom, and the non-uniform design of the laying length of the reinforced body in the reinforced soil structure is completed. When the rear part of the reinforced soil structure is limited by space, the reinforcement body can be laid non-uniformly, so that while the stability of the reinforced soil structure can be satisfied, the usage of the reinforcement body in the reinforced body structure can also be saved.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a design method for non-uniform laying of reinforced bodies in reinforced soil structures. Background technique [0002] Reinforced soil structures are currently widely used in civil engineering, transportation and other engineering. Reinforced soil technology is to make the soil stable and act as a retaining structure by laying geosynthetics (ie, reinforced body) in the soil. For the reinforced body to play a role, it needs to have sufficient strength. At the same time, the laying length must be long enough so that the reinforced body has a certain length of anchoring section, so that the reinforced body can exert its strength. [0003] At present, in the internal stability design methods of reinforced soil structures, it is required that the reinforcement body be laid with uniform length in the height direction of the reinforced soil structure, or that the sec...
