Dependence of stress-strain state of hydraulic structures on infiltration moistening of foundation soils

Abstract

As is known, loess subsidence soils are widespread on the globe; their area in Europe and Asia is more than 13 million sq. km. Many of the loess rocks are also located in Central Asia, including the Republic of Uzbekistan. The practice of irrigation development of loess lands shows that the disruptions that have occurred so far in the operation of hydraulic structures (HTS) are due to insufficient knowledge and neglect in designing the features of joint work and interaction structures with their subsidence foundations. The design of hydraulic structures also does not fully consider these features. To ensure the long-term, reliable, and economical operation of hydraulic structures on subsiding soils, it is necessary to improve their design and construction methods, considering the peculiarities of interaction with loess foundations. This article deals with the features of infiltration soil moistening from channels and structures on them. The article deals with the features of the infiltration moistening of soils from canals and structures on them. Based on the analysis of previous studies, the specificity of infiltration in loess soils is considered a serious factor affecting the stress-deformed state of hydraulic structures and their foundations.
