Prenn Pass is an important transportation route connecting Da Lat City with surrounding areas. Located in mountainous terrain with steep slopes, the route is affected by complex geological conditions as well as surface water and groundwater. Therefore, slope stability and landslide mitigation are critical to ensuring the safety and long-term performance of the infrastructure.
At the Prenn Pass Landslide Stabilization Project in Lam Dong Province, Vietnam, PET Geogrid 200/100 kN and APT 25 Nonwoven Geotextile were used as part of the geotechnical solution for soil reinforcement and slope stabilization.
Application of An Thai Fiber Geosynthetic Solutions at the Project
The combination of PET Geogrid and APT 25 Nonwoven Geotextile provides complementary functions including soil reinforcement, separation, filtration and drainage, contributing to the overall stability of the treated slope structure.
PET Geogrid 200/100 kN for Prenn Pass Landslide Stabilization
PET Geogrid is a geosynthetic reinforcement manufactured from high-tenacity polyester (PET) yarns, providing high tensile strength and good long-term performance for reinforced soil applications.
At the Prenn Pass Landslide Stabilization Project, PET Geogrid 200/100 kN was used as reinforcement within the soil structure.
When installed within compacted fill in accordance with the engineering design, PET Geogrid interacts with the surrounding soil and mobilizes its tensile strength. This reinforcement mechanism helps control deformation, limit displacement and improve the overall stability of the reinforced soil mass.
For transportation infrastructure and geotechnical works, PET Geogrid is commonly used in applications including:
-Soil reinforcement;
-Road and highway reinforcement;
-Slope reinforcement and stabilization;
-Reinforced soil structures;
-Reinforced retaining structures.
The required tensile strength, reinforcement length, vertical spacing and installation arrangement of the PET Geogrid should be determined based on geotechnical calculations, site conditions, design loads and applicable technical standards.
APT 25 Nonwoven Geotextile for Separation, Filtration and Drainage
In combination with PET Geogrid, APT 25 Nonwoven Geotextile was used at the Prenn Pass project to provide separation, filtration and drainage functions within the structure.
APT 25 Nonwoven Geotextile separates material layers with different properties, helping prevent intermixing between the subgrade soil and overlying materials while maintaining the intended performance of each structural layer.
Its filtration properties allow water to pass through while retaining soil particles according to design requirements, helping control soil migration and support drainage within the structure.
The combination of PET Geogrid 200/100 kN and APT 25 Nonwoven Geotextile therefore provides complementary functions within the landslide stabilization solution: reinforcement from the geogrid, together with separation, filtration and drainage from the nonwoven geotextile.
Applications of PET Geogrid and Nonwoven Geotextile
PET Geogrid and Nonwoven Geotextile are widely used in transportation and civil engineering projects where reinforcement, separation, filtration and drainage are required.
Typical applications include:
-Roads and highways
-Railway infrastructure
-Slope reinforcement and stabilization
-Reinforced soil structures
-Retaining structures
-Soft ground improvement
-Infrastructure projects under challenging geotechnical conditions
The selection of PET Geogrid, Nonwoven Geotextile and other geosynthetic materials should be based on project-specific geotechnical conditions, design requirements, mechanical and hydraulic properties, and applicable technical standards.
