The Importance of PVD in Soft Soil Consolidation

Oct 13, 2025 by talynt.org 23 views

Introduction

Soft soil is a type of soil that is formed through the weathering process and has less supportive characteristics for development. This soil has a binding power between weak particles, high water content, low permeability, and high compressibility. All of these factors cause soft soils to tend to experience a significant decline for a long time. Therefore, appropriate soil repair techniques are needed to support construction on soft soil. One of the commonly used techniques is prefabricated vertical drain (PVD).

The Importance of PVD in Soft Soil Consolidation

In the construction project of the Behandle area of Kuala Tanjung Port, the use of PVD is an effective solution to overcome the problems faced by soft soil. With the application of PVD, drainage flow can be done vertically, so that pore water can be released faster. This is very important to accelerate the process of soil consolidation and reduce the risk of excessive decline after the construction is complete. The use of PVDs has been proven to be effective in reducing the time needed for consolidation, thereby increasing efficiency in infrastructure development.

Methodology

In this final project, after the required data collection, analysis of analytical calculations and the use of the plaxis program to evaluate land reduction and time needed to achieve a degree of consolidation of 95%. Data obtained from analytical methods, plaxis programs, and field observations are then compared to getting a more comprehensive picture of the effectiveness of the use of PVD in the process of soft soil consolidation.

Data Collection and Analysis

The calculation results show that with a decrease of 0.932 meters, soft soil without the use of PVD requires a very long time, which is 3824 days to reach 95% consolidation. Conversely, the use of PVD significantly speeds up this process, with a consolidation time that only requires 81 days. From this, it can be concluded that the use of PVDs is very effective in accelerating the process of soft soil consolidation.

Results and Discussion

However, the results of the analysis also showed a striking difference between the estimated decline obtained through analytical methods and data from the plaxis program. The decrease calculated analytically is much smaller, which is 1,7033 meters, compared to the decrease produced by the plaxis program, which is 1,722 meters. This shows that analytical methods tend to be conservative and may not fully describe the actual conditions in the field.

Comparison of Analytical and Plaxis Program Results

The use of PVDs in this project has been proven to reduce the time needed for consolidation, thereby increasing efficiency in infrastructure development. By understanding and implementing this technology effectively, construction projects on soft soil can be done more securely and on time. This is an important lesson for engineers and planners involved in development in locations with similar land conditions.

Conclusion

Overall, this analysis provides a clear picture of the importance of soil improvement techniques, especially the use of PVDs, in construction projects on soft land. In addition, the ratio between analytical and sophisticated software methods such as plaxis shows how important the selection of appropriate methods is to support decision making in the field.

Recommendations

The use of PVDs in construction projects on soft soil is highly recommended. This technology has been proven to be effective in reducing the time needed for consolidation, thereby increasing efficiency in infrastructure development. Engineers and planners involved in development in locations with similar land conditions should consider implementing this technology effectively to ensure the success of their projects.

Future Research Directions

Future research should focus on the development of more advanced soil improvement techniques, such as the use of geosynthetic materials and advanced drainage systems. Additionally, the use of machine learning and artificial intelligence algorithms to optimize the design and implementation of PVDs should be explored.

Limitations of the Study

This study has several limitations, including the use of a single case study and the limited scope of the analysis. Future research should aim to address these limitations by conducting a more comprehensive analysis of the effectiveness of PVDs in soft soil consolidation.
