RESEARCH ON EVALUATING THE STABILITY OF EMBANKMENT STRUCTURES AT BUN XANG LAKE UNDER CHANGING WATER LEVELS DUE TO TIDAL AFFECTS.
Tóm tắt
This research aims to assess the stability of the Bung Xang Lake embankment in the context of changing water levels due to change climate, specifically recent high tides. In this research, data from two cross-sections were collected and analyzed using Plaxis 2D V22 software. The simulation results indicate that the piles with a length of 11.30 meters, as per the design, still fall within the deformation range of the subsoil, especially at the surveyed location with weak and thick geological conditions (MC2-2), which limits the effectiveness of the piles. However, the stability analysis results at two representative cross-sections show that the overall stability factor of the embankment structures ranges from 1.380 to 2.618, which falls within the allowable limits according to the Vietnamese standard TCVN 9902:2013. The analysis results of this research showed that the embankment system is ensured and complies with the current Vietnamese standards.
