“…The contact between the structure and the ground must be taken Sustainability 2024, 16, 899 2 of 12 into account when designing and constructing facilities using the sinking well technology. The likelihood of problems during construction should be taken into account, which is related to the need to determine the design assumptions for the subsoil [6]. The identification of the subsoil and the determination of subsoil properties are significant steps in the development of a construction project.…”

Sinking wells belong to underground facilities. Large-diameter sinking wells are often constructed as retention basins and reservoirs for wastewater treatment plants, which is determined by the Urban Wastewater Treatment Directive. The directive obliges Member States to implement the principles of sustainable development, promoting sustainable sewage collection and treatment systems. When designing and constructing facilities using sinking well technology, contact between the structure and the ground must be considered. During the lowering of a sinking well into the ground medium, a number of negative impacts may occur and affect the sinking process, including excessive ground settlement outside the well, damage or destruction of adjacent objects, tilt of the well casing from the vertical, and uncontrolled sinking of the well casing. The aim of this paper is to determine the occurrence of negative impacts during the lowering of sinking wells. Determining the incidence of negative impacts could help to avoid pre-failure and emergency situations relating to sinking wells. A fuzzy TOPSIS method was used to determine the above.

“…Slope reinforcement is helpful to ensure the stability of geotechnical engineering slopes, which is an important measure to ensure the stability of slopes, and can also essentially eliminate the adverse factors of slope stability [6]. The choice of the slope reinforcement scheme has an important influence on the prevention and control of landslide disasters [7]. A reasonable reinforcement scheme can improve the economy and safety of landslide disaster prevention and control [8,9].…”

Numerical Investigation of a Local Precise Reinforcement Method for Dynamic Stability of Rock Slope under Earthquakes Using Continuum–Discontinuum Element Method

The slope reinforcement scheme has an important influence on the prevention and control of landslides. A reasonable reinforcement scheme can improve the reliability, economy and efficiency of landslide resistance. It is urgent to establish a local precise reinforcement method for landslides on the basis of clear process and the instability modes of landslides. Taking a high-steep anti-dip rock slope as an example, six numerical models are established by using the continuum–discontinuum element method (CDEM) to carry out seismic damage and dynamic analysis of slopes. By comparing the seismic response and damage characteristics of being unstrengthened, local precise reinforcement and overall reinforcement models, the applicability of the proposed local precise reinforcement method for the slopes is discussed. The results show that the determination of the dynamic amplifying effect and seismic damage characteristics of slopes is the primary prerequisite of the local precise reinforcement method. The dynamic amplification effect of the slope toe, crest and shallow slope surface are much larger, that is, they are the potential reinforcement areas. The local precision reinforcement times should be controlled within a certain number of times, and the slope after the first three times of the local reinforcement effect is the best. However, more than three times after the reinforcement effect it becomes worse. Moreover, the dynamic amplification effect, the equivalent crack ratio and the mechanical energy of the slope after three times of local precision reinforcement are similar to the overall reinforcement effect, which indicates that local precision reinforcement has good feasibility. This work can provide references for landslide disasters prevention and control.

“…In order to give stability to the cut, anchored diaphragm wall panels oriented towards the slope were used. This is an unusual solution, because underground walls are primarily used as a securing and sealing element in deep excavations and foundations of buildings either for temporary excavation support or as part of the permanent structure [4][5][6][7]. Currently, the construction of individual diaphragm wall panels is being carried out on the construction site, and the upper part of the wall is being dug out for the purpose of its multi-level anchoring.…”

The route of the D1 highway in the Lietavská Lúčka - Dubná Skala section near Žilina is taken forward by a 17 m deep cut in a section about 300 m long. The first proposed solution of the highway route was based on the assumption that it is a stable area. However, during the construction of the highway cut an old landslide area with a depth of shear surfaces of up to 25 m was identified right in the area of the cut. Therefore, massive measures had to be designated to assure that the area above the highway and the access to the tunnel portal were not threatened by landslides. When addressing the security of the cut, an unusual solution was used - anchored diaphragm wall panels of underground concrete walling oriented towards the slope. Currently, this given solution is under construction and is controlled by inclinometers incorporated into selected diaphragm wall panels.
