Plant Root Reinforcement Effect for Coastal Slope Stability

Wang, Y.; Shu, Z.; Zheng, Y., and Xiao, S., 2015. Plant root reinforcement effect for coastal slope stability.

As an advanced engineering technology, root reinforcement has been practically applied in the coastal slope protection, but the theoretical study has lagged behind. Based on the geotechnical engineering slope theory and plant ecology, it is still needed to apply new root-soil interaction and mechanical models to provide approaches for the numerical analysis on slope stability. As the plant roots growth is complicated and changes with the coastal rock and soil, it is important to use accurate methods to assess root strengthen ability. According to the slope protection action mechanism of the vegetation and the stress-strain pattern analysis, the model of reinforcement mechanism is established to deduce the general mathematical equation of the root systematic resist-slipping stress to provide a theoretical basis for coastal slope protection design.
