Has anyone worked on additives for aerated blocks?

The stability of a slope is usually expressed as the ratio of the resisting force (Fs) on the sliding surface to the sliding force (Fr), that is, the resistance stability coefficient (η). The larger this ratio, the more stable the slope is ； Conversely, the steeper the slope, the less stable it is. The common methods for evaluating slope stability are divided into the following 4 categories: ① Qualitative analysis methods. By studying the dimensions and slope shape of the slope, its geological structure, the geological environment in which it is located, its geological history of formation, signs of deformation and failure, as well as various factors affecting its stability, it is possible to determine the evolution stage and stability condition of the slope. ②Limit equilibrium analysis method. The rock and soil masses that may slide are assumed to be rigid bodies. By analyzing the possible sliding surfaces and simplifying the stresses on those surfaces as being uniformly distributed, the stability coefficient of the slope can be calculated. ③Numerical analysis method. Using the finite element analysis method, the slope displacement field and stress field are first calculated, and then, based on the strength criteria for rocks and soils, the stability coefficients of each element relative to the potential sliding planes are determined. ④Engineering geological analogy method. An analogy is drawn between the slope under study or the artificial slope to be designed and slopes that have been studied or for which there is existing experience, in order to evaluate its stability and determine appropriate slope heights and angles.
