Description of the project
This road connects the territory of the entire microdistrict Monastyrska Gora (formerly the village of "Chervony Shlyakh") with the center of Poltava and the main infrastructure of the city. Also, this road is the shortest route to the Khrestovozdvyzhensky Monastery from most of the city. Due to a landslide from the mountain, traffic on the street is currently blocked and a detour has been arranged. Under these conditions, residents of the microdistrict Monastyrska Gora do not have a direct connection with the city, which creates significant difficulties in people's daily lives, increases the traffic load on the roads of the Dalni Yakivtsi microdistrict and on the road through the Dendropark. Most of the territory of the microdistrict – This is a residential area of private houses, which indicates that its population depends on the city's infrastructure, the majority works outside Monastyrska Gora, children go to school in the city. The emergency area, which blocks the connection of the microdistrict with the city, requires repair work, which is provided for by the project documentation.
Also, due to the collapse of the soil, there is a threat of destruction of the Khrestovozdvizhensky Monastery and the mountain on which it is located. In this regard, the question of carrying out a major repair of the section of Paisii Velichkovsky Street within the emergency area, from Luhova Street to the junction with Lysenko Street in Poltava arose. Active landslide processes are taking place within the slope. In this regard, the territory is classified as landslide-prone. The formation and development of landslides has a natural origin. At the same time, man-made intervention, in the form of slope planning, laying communications and concentrated soaking of soils, provoke the intensification of landslide processes.
Regarding the development of the landslide, previously, attention was mainly paid to damage to the road leading from Podil to the village of Chervonyi Shlyakh. The road was most often deformed, and its repair, at all times, was carried out by filling in additional soil, which was formed after the landslide was activated, and since this is the main part of the landslide, repair work again formed the conditions for the further development of the landslide process. The landslide refers to sliding landslides. The thickness of landslide accumulations is mainly from 1.0 to 8.0 m. According to the complexity of engineering and geological conditions, the area of the works belongs to category III (complex). The latest landslide activation in the repair area began in the second half of 2023 and continues to this day. Over the last period, it has been possible to reduce the speed of landslide movement by removing part of the soil from the upper part of the slope (below the road), but the development of landslide processes in the lower part of the slope continues. Currently, the project area is in an emergency state. Active landslide processes are occurring within the slope. The asphalt concrete pavement has been destroyed.
To prevent negative manifestations in the form of the development of landslide processes and planar washout, the project has developed a set of measures for engineering protection of the territory, which includes active anti-slide retaining structures, a drainage system for surface and underground runoff, and the organization of a surface drainage system.
