Introduction

Toll road construction projects are often faced with soft soil challenges that can hamper the smooth running of construction. Soft soils have easily deformized and vulnerable properties to significant decreases, so that they require special improvement techniques. In the Medan-Kualanamu toll road project Km 35+622.42, the use of the prefabricated vertical drain (PVD) and geotextile methods is a solution to overcome soft soil problems. Understanding the importance of soft land repair is crucial in ensuring the stability and safety of construction projects.

Understanding PVD and Geotextile in Soft Land Repair

PVD, also known as a vertical drain of prefabrications, is an effective method for accelerating the process of soft soil consolidation. The principle of working is to create a vertical drainage path that allows excess pore water to be anticipated quickly. This reduces the time needed to achieve soil consolidation and allows construction to be continued faster. The use of PVD has been widely recognized as a reliable solution for soft soil problems.

Meanwhile, Geotextile acts as a filter and soil booster. Its function is to prevent erosion and increase soil shear strength. In other words, geotextile helps the soil become more stable and able to withstand greater loads. Geotextile plays a crucial role in ensuring the stability of soft soils.

In-depth Analysis: Looking for optimal PVD space spacing

To determine the optimal PVD space spacing, an analysis is carried out using analytical methods and element methods up to. This study aims to find a combination of spacing spacing and PVD installation patterns that produce the fastest consolidation time. The analysis of PVD space spacing is a critical factor in determining the effectiveness of soft land repair.

The analysis results show that the smaller the space space between PVDs, the faster consolidation time. The pattern of triangle installation is also proven to be more effective than a square pattern, thus providing a more equitable drainage distribution. The findings of this study provide valuable insights on the optimal PVD space spacing.

The importance of cost considerations in planning

Although the analysis shows that the smaller spacing of PVDs results in a faster consolidation, it should be remembered that the cost factor also needs to be considered in planning. The smaller space spacing means the number of PVDs needed is more, and this will increase construction costs. The cost factor is a critical consideration in determining the optimal PVD space spacing.

Therefore, it is important to find a balance between consolidation time and construction costs. Comprehensive cost analysis must be done to determine the optimal PVD space spacing in terms of economic. The importance of cost considerations in planning cannot be overstated.
