Geotechnical Mapping for Soil Physical and Mechanical Parameters and Hard Soil Depth in Badung Regency

Abstract

The infrastructure is important for the great life of a region and most of the country. Therefore, infrastructure must be always in proper condition in its functionality. Furthermore, it must follow the main principle which is infrastructure asset management. In this case, geotechnical mapping is also related to the principles of Infrastructure Asset Management in planning, designing, and feasibility studies of an infrastructure project in Badung Regency, hence the infrastructure projects are better prepared. The research methods include collecting soil investigation data, processing soil investigation data, describing the results of soil investigation data with mapping tools, and geotechnical zoning with statistical analysis. The results obtain a geotechnical map of Badung Regency in 2 and 3-dimensional forms. The 2D results in the form of a hard soil depth map can be concluded that South Kuta District has a variable depth of 0.4 -15 meters, North Kuta District has a variable depth of 1.5 -5 meters, Kuta District has a variable depth of 1.5 -10 meters, Mengwi District has a variable depth of 1.5 -10 meters, Abiansemal District has a variable depth of 5-15 meters, Petang District has a variable depth of 5-22 meters. The 3D Zone 1 lithology map can be concluded that the Zone 1 area covered with a hard soil depth of around 5 -10 meters is dominated by sandy silt, silty sand, sand, and a little clayey silt. That area covered with a hard soil depth of about 1.5 -5 meters is dominated by clay, clayey silt, sandy silt, silty sand, and sand with a heterogeneous distribution. The Zone 1 area is dominated by the specific volume saturated value (γsat) range of 1.5 -2.0 t/m3. The values > 2.0 t / m3 are found in Sading area with a hard soil depth of 5-10 meters. The Zone 1 area is dominated by the range of N-SPT values = 0 -30. The N-SPT values > 30 are found in Sading area with hard soil depths of 5-10 meters.

Determination of Optimum Mixture Between FABA and Local Fill Soil for Road Embankment. Case study: Road Preservation of Sp. Kereng - Bereng Bengkel – Pilang – Pulang Pisau, Central Kalimantan

“…As a result, maintaining infrastructure in optimal functional condition is crucial. This involves adherence to the fundamental principle of infrastructure asset management (Maulidha et al, 2022). To address this issue, the Ministry of Public Works and Housing through the National Road Implementation Agency for Central Kalimantan Region has been implementing a road preservation program annually.…”

“…The science, program, and expertise for managing facilities and infrastructure across the course of their lives is known as infrastructure and facility asset management, or IFAM. IFAM's primary goal is to guarantee that facilities and infrastructure may operate in an economically, efficiently, and effectively sustainable manner while adhering to ecologically friendly principles (Maulidha, Satrya & Lastiasih, 2022).…”

“…As a result, maintaining infrastructure in optimal functional condition is crucial. This involves adherence to the fundamental principle of infrastructure asset management (Maulidha et al, 2022). Recognizing the importance of this infrastructure, the construction of the Serang-Panimbang Toll Road is currently ongoing in Banten province.…”
