    Abstract
  • Due to space limitations, a slope project in Guiyang requires vertical excavation. Because the slope is adjacent to the original water plant buildings and structures, the slope deformation needs to be strictly controlled. Therefore, the inclined chair pile-anchor support system was proposed. Through numerical simulation, the stability of the slope after supporting, the displacement control during construction, and the stress characteristics of the support structure were discussed. The results show that the supporting system has reasonable stress and a good deformation control effect. The monitoring results show that the maximum cumulative displacement of each measuring point of the slope section is in a small range, the deformation is gradually stable, the inclinometer curve tends to converge, and the field treatment measures have obvious effects. After the completion of the slope project of the Eastern Water Plant, the operation status was good. On the premise of ensuring the site space, it effectively protected the safety of the existing water plant at the top of the slope. The inclined chair pile anchor support scheme adopted can be used as a reference for similar projects.
