Investigations on the Stability of the Right Slope in the Area of Anina Wastewater Treatment Plant

Abstract

Often, excavations of natural slopes are necessary in the site area for the construction of civil or industrial objectives. The execution of such works requires special attention, from the design phase, regarding the stability of the slope in the initial state, but also after excavation and identification, if necessary, of technical solutions to increase the stability reserve, thus ensuring the security during the execution of works but also of future constructions. Such a situation was encountered in the case of Anina Wastewater Treatment Plant (WWTP), when, in the absence of proper investigations of the slope to be excavated, there was a landslide that interrupted the site activities, and which, to some extent, jeopardized the objectives already built. In this context, at the level of 2015, slope stabilization works were designed and executed, works that proved to be insufficient. In 2021, it was necessary to conduct a new stability study in order to analyze the possibilities of continuing the construction of the treatment plant. This paper presents the results obtained during this study, as well as a series of conclusions and interpretations, regarding the technical condition of the slope in different hypotheses.

Analysis of the Stability State of Jilț North Internal Dump in the Perspective of its Ecological Reconstruction

“…The first is based on an algorithm for diagnosing the degree of soil recovery (the pedogenesis process) [37], and the second on a species selection procedure [1,38] based on the results obtained by applying the algorithm, but which may also include other relevant variables (distance to water sources, environmental risks such as wildfires, prolonged droughts, floods, etc. ).…”

Study of the Multi-Critical Parameters Characterizing the Instability Behavior of Translational Rockslides Considering the Excavation

“…Among various human engineering activities, slope excavation engineering is one of the most commonly seen activities triggering landslides [9][10][11]. The slope excavation-induced landslides are usually characterized by translational movement, where the rock slopes are prone to slides along the 2 bedding planes of underlying strata aligned in a subparallel manner to topography [12][13][14][15].…”
