MECHANISM AND ABILITY ANALYSIS OF PLANT ROOT REINFORCEMENT IN SLOPE PROTECTION

Abstract The stress，which acts on the plant root in the crag earth medium，has the characters of extreme complexity and polytropy，so the determination of its reinforcement ability is considerably difficult. According to the slope protection action mechanism of the vegetation and the stress-strain pattern analysis，the model of reinforcement mechanism and the general mathematical formulae of the root system¢s resist-slipping stress，and the plant root system¢s reinforcement ability are established.
