“…However, application of the basic LBM formulation to combustion is limited to low Mach number reactive flows [44,45,46], which is unsuitable for detonations with high compressibility. More sophisticated formulations can be constructed to solve the discrete Boltzmann equation for nonreactive [47,48] and reactive flows [49,50] by separate discretization of time, space and particle velocities. In particular, the discrete Boltzmann method (DBM) introduces higher-order kinetic moments so that the hydrodynamic and thermodynamic fields are fully coupled.…”

“…At present, the research on debris flow siltation primarily focuses on the deposition range and deposition characteristics of debris [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Tian et al analyzed the submerged range of the debris flow siltation in the Qinglin Basin through numerical simulation [ 22 ], and Vosoughi et al studied the depth of debris flow siltation through field observation as well as numerical modeling [ 23 ].…”

In recent years, the resulting siltation from railway debris flow disasters has seriously affected the normal use of railway traffic lines and brought great challenges to rescue work. In view of this, we used an orthogonal test scheme to prepare different types of debris flow accumulation and carried out penetration resistance tests in order to explore the effects of different types of curing agents, the amount of curing agent added, the moisture content of debris flow siltation, and the grain gradation of debris flow sediment on the solidification strength of debris flow siltation. We also utilized scanning electron microscopy (SEM) to observe the microstructure and potential curing mechanism of the samples treated with different curing agents in attempt to discern the reasons for their different levels of strength. Our results show that the each of four curing agents tested can effectively improve the solidification strength of the siltation. Furthermore, we found that the type of curing agent had the largest impact on the curing strength of the siltation, followed by the moisture content of the siltation itself, the amount of curing agent added, and particle size. To achieve the best results, we recommend using 14% sulfoaluminate cement as the curing agent.
