Abstract

Soft soil problems are common in Indonesia. This study is based on a case study of soft soil problems in Cibitung, Bekasi. The determination of treatment to improve the soil needs to be done based on field data results. Determination of repair options includes the type of construction, soil type conditions, time, cost and feasibility of a method. Based on soil conditions with a soft soil thickness more than 2m, need such as PVD or slab on pile treatment. If it is less than 2m, soil mixing or replacement can be option.

Abstract

Infrastructure development in Indonesia often faces rugged terrain and high seismicity, requiring advanced geotechnical solutions. One of the challenges lies in ensuring that an embankment can effectively withstand heavy loading conditions. Mechanically stabilized earth (MSE) walls provide a safe and efficient option to address these RSS with a total height of 26.95 meters based on a previous project. The structure is designed to withstand a large static surcharge load (up to 375 kPa) and a seismic load with a peak horizontal ground acceleration (kh) of 0.225g. The method employed is a limit equilibrium stability analysis using Janbu's simplified method of slices for non-circular failure surfaces, referring to the SNI 8460:2017 standard, and utilizing TensarSlope software. The selected system is the SierraScape System, which combines high-strength uniaxial geogrid primary reinforcement with a flexible welded wire for facing. The analysis results show that the retaining wall design meets the required factors of safety for both static (FS = 1.301 > 1.300) and seismic (FS = 1.163 > 1.100) conditions. In conclusion, this case study demonstrates that the application of modern geosynthetic reinforcement systems is a reliable and effective solution for addressing geotechnical challenges in high-risk projects in Indonesia, contributing a design reference for similar conditions.

Abstract

The majority of building and civil engineering projects start on undeveloped soils. Before taking any further action, a thorough site inspection is required to determine the current condition of the site. Finding a location with optimal soil conditions can be difficult. One of the most commonly used methods for treating undeveloped soil is to incorporate natural fiber to reinforce soil, also known as natural fiber-reinforced soil. The purpose of this review article is to look at how different natural fibers reinforced soil. A review of studies suggests that reinforcing soil with natural fibers is a low-cost and effective stabilizing technique with several benefits. This paper is intended for geotechnical engineers in improving undeveloped soils with natural fibers, as well as researchers conducting future research.
