ABSTRAKAda beberapa jenis perkuatan tanah untuk mengantisipasi longsoran yang sering digunakan di Indonesia seperti halnya geotekstil. Analisis stabilitas dilakukan pada lereng timbunan dengan kemiringan 1V:1H, 1V:1,5H dan 1V:2H dengan membandingkan kondisi lereng timbunan tanpa perkuatan geotekstil, lereng timbunan dengan perkuatan geotekstil serta lereng timbunan dengan perkuatan geotekstil yang dipengaruhi oleh termal menggunakan software PLAXIS 2D 2017. Analisis pengaruh termal dilakukan dengan memvariasikan besaran nilai suhu dan parameter termal tanah (kapasitas, konduktivitas dan ekspansi). Terjadi penurunan stabilitas lereng timbunan dengan perkuatan geotekstil yang diakibatkan oleh semakin besarnya nilai suhu termal dan terjadi peningkatan stabilitas lereng dengan perkuatan geotekstil akibat meningkatnya nilai ekspansi termal, sedangkan nilai konduktivitas dan kapasitas termal tidak berpengaruh.   Kata kunci: lereng timbunan, geotekstil, stabilitas, suhu, parameter termal tanah. ABSTRACTThere are several types of soil reinforcement to anticipate landslide that are often used in Indonesia as well as geotextile. The stability analysis is carried out on the slope of the embankment with a slope of 1V:1H, 1V:1,5H and 1V:2H by comparing the slope conditions of the embankment without geotextile reinforcement, slope of embankment with geotextile reinforcement and slope of embankment with geotextile reinforcement that influenced by thermal using PLAXIS 2D 2017. The thermal effect analysis is carried out by varying the value of temperature and soil thermal parameters (capacity, conductivity and expansion). There is a decrease in the stability of the embankment slopes with geotextile reinforcement caused by the increasing thermal temperature value and an increase in slope stability with geotextile reinforcement due to the increase of thermal expansion value, while the conductivity and thermal capacity have no effect.Keywords:  embankment slope, geotextile, stability, temperature, thermal soil parameter.

The Stability

The traditional limit equilibrium method in the analysis of slope stability not only exists some subjective empirical hypothesis that can not meet the equilibrium of force and moment, but also ignores the effects of internal stress and strain on the slope stability. Furthermore, in the stability of the slope evaluation, limit equilibrium method relies too much on experience when hypothesizing the slope slip surface. So that it makes deviation on slope analysis and stability evaluation. This paper is based on simplified Bishop method used to establish the model of slope stability analysis. And it used genetic algorithms to solve the minimum safety factor and the most dangerous slip surface of slope. It was the arithmetic which simulates organisms genetic evolutionary process and it avoided the traditional methods falling into the local extreme value point easily and error propagation leading to convergence. The algorithm had advantages of higher accuracy, quick convergence and applicability. It showed that the genetic algorithm is accurate and reliable in the analysis of slope stability.

Cracked Soil

Many studies have begun to develop the concept of cracked soil. The results of research related to cracked soil are able to answer the irregularities that occur, such as the difference in the results of the stability analysis which is considered safe with the conventional bishop method, while the conditions in the field are landslides. Swelling soil is soil that is susceptible to changes in water content. This type of soil is very prone to cracking. To build infrastructure on the swelling soil type, an improvement must be made, one of which is by mixing the swelling soil with biopolymer. The results of this biopolymer mixing are then modeled in the New Slope Stability Analysis Program (NSSAP) 1.0 which refers to the concept of cracked soil. From the analysis, it was found that the slope safety factor before improvement with biopolymer was 0.305 and the safety factor after improvement with biopolymer was 2.006. From the results of this study, it can be seen that the role of biopolymers in stabilizing swelling soil is quite large, which is around 558%.

The proposed Kathmandu-Hetauda Road alignment passes through Thankot, Chitlang, Kulekhani, Bhimphedi, and Bhaisedobhan. It is the shortest as well as least hazardous route very suitable for a standard highway. It has the following three tunnel sections: the Thankot Tunnel (3.2 km long), the Kulekhani Tunnel (500 m long), and the Chisapani Tunnel (3.8 km long). The alignment passes through the Kathmandu Nappe, Upper Nawakot Group of the Lesser Himalaya, and the Siwaliks. It also crosses the Main Boundary Thrust and the Mahabharat Thrust, four major faults/shear zones, and a major fold axis. The areas of plane sliding, wedge sliding, and toppling are delimited on the basis of the study of discontinuities along the proposed alignment. The stability analysis show s that 60-75% of the total road length is stable, 20-30% is fair, 5- 15% is weak, and 2-5% is critical.

The Stability

The slope stability analysis is always under severe threats in many parts of nilgiris district, causing disruption, loss of human life and economy. The stability of slopes depends on the soil shear strength parameters such as Cohesion, Angle of internal friction, Unit weight of soil and Slope geometry. The stability of a slope is measured by its factor of safety using geometric and shear strength parameter based on infinite slopes. In this research, investigation was carried out at 5 locations in Kattery watershed in nilgiris district. The factor of safety of the slope determined by Mohr Coulomb theory based on shear strength parameter calculated from direct shear test which is a conventional procedure for this study. Artificial. Neural Network (ANN) Model is used to predict the factor of safety. The input parameters for the (ANN) are chosen as Cohesion, Angle of internal friction, Density and Slope angle and the factor of safety as output. The results obtained in ANN method were compared with that of conventional method and observed a good agreement between these two methods.
