A simple analytical model for bamboo-reinforced slopes using modified Bishop method

Introduction: Embankments are constructed in many places for transportation purposes such as railways and roads. The stability of slopes embankments has always been a concern, especially cohesionless soils. There methods to increase the safety factor soil using geogrids, geocells, concrete piles, so on. conventional material used stabilize huge impact on environment. Nowadays, researchers natural fibers bamboo coir fiber stabilization purposes. Methods: In this paper, piles slopes. inserted vertically slope face shear strength against failure. A limit equilibrium method developed estimate improved by friction after modifying Bishop slices. is analyzed both reinforced conditions unreinforced analytical formula. Results Discussion: equations were considering three modes failure: failure along surface, movement upper part soil, leaving pile embedded base pulling out with mass. Further validation results carried method-based software SLOPE/W modified method. increased reinforcing all modes.
