Abstract:: Based on the soil and water conservation of highway slope and the entire ecosystem of rice straw and other waste recycling purpose, the full ecological rope net slope protection structure which can prevent rainfall erosion has been developed. Through erosion tests of self-developed indoor simulated side-slope erosion devices, various parameters such as velocity of water flow scouring the surface of the slope, amount of sediment and the rainfall penetration have been compared and analyzed. The mechanism of rainfall erosion for rope net protection has also been examined and the optimal parameter has been screened. Through rope net slope protection field test, the rope net application effect on slope protection and straw rope net changes of decay in high temperature and rainy southern region are obtained. Compared with the unprotected bare slope, the slope with rope net protection can slow slope flow velocity by 20% ~ 50%, reduce more than 60% of sediment erosion caused by heavy rainfall. It shows that the performance of the rope revetment was better than the groundwork lattice revetment under the same circumstance, while the rope revetment could also increase the infiltration of waterfall, which would be beneficial for the conservation of water and soil.
