It is essential to cast light on the construction risks in tunnel Dosing Funnel excavations through the fault-fracture zone (FFZ).This study adopts the material point method (MPM) to simulate the failure responses of a rock tunnel face during excavation through the FFZ.A numerical study was conducted to compare a physical model test and validate th
Many engineering structures have been built on the sandstones.The main purpose of this study is to estimate the uniaxial compressive strength (UCS) and modulus of elasticity (Es) of sandstones using regression models.For this purpose, petrographic studies, compressional wave velocity (Vp), porosity, density and uniaxial compressive strength tests w
In many areas of the economy, Dosing Funnel we deal with random processes, e.g., transport, agriculture, trade, construction, etc.Effective management of such processes often leads to optimization models with random parameters.Solving these problems is already very difficult in deterministic cases, because they usually belong to the NP-hard class.I
BackgroundIn the past decade, the number of reported cases of scrub typhus (ST) has increased dramatically in Sichuan Province.We aimed to overview the epidemiological characteristics of ST, identify the variables contributing to the spatial distribution, and estimate the risk areas of ST occurrence.MethodsDaily ST cases reported at the county leve
