Reinforcement Theory And Engineer Application Of Anchor-rope Beam In Cutting Slope Of Jin-wen Railway

Instability ruin of slope, a main geologic disaster, is one of human-faced three natural disasters. Because railway subgrade is affected by geologic structures, characteristics of rock and soil, terrain, weather outcome and human activities, it's a long-term un-solved problem to judge, analyze and father efficiently.This thesis puts emphases on the research of slope stability of Jin-wen Railway. And combined with limit equilibrium and finite element method, it discusses either distinguishing condition of slope destroy or value simulated method when tendon and rock co-act. And major researches in this paper are as follows: the characteristics of Jin-wen Railway subgrade slope and factors on slope stability are analyzed; Janbu method slope stability analysis is known as a reinforced theory in detail; it is dicussed that an equivalent plastic strain run-through area is confirmed making use of finite element method,which acts as a potential slope surface, furthermore a slope traditional stability coefficient by Janbu method is gained; a slope stability analysis idea is given combined with value technique and limit equilibrium method and at the same time, prestress tendon reinforced slope mechanism is described briefly. Finally, theory explanation is carried linking two engineering application examples.The thesis analyzes and researches slope stability and tendon girder structure forced applied with limit equilibrium analysis method and finite element method based on Jin-wen Railway cutting slope fathering engineering. and two-stage design method of girders according to forced stages, which optimizes engineer design and incarnates reinforced slope dynamic design thought..
