Plans choices of ecological engineering of mountain highway slope based on catastrophe progression method

Slope engineering is a typical problem of mountain highway and ecological slope protection is a widely used engineering technology in current construction. For the best choice of ecological slope protection in mountain highway construction, multi-level evaluation indexes system on ecological bank is firstly established according to multi-dimension evaluation principles and decision model is then figured out based on catastrophe progression method. Application in construction suggests that the evaluation model is a simple decision way to evaluate ecological bank plan comprehensively, which has better practicality and reflects facts in construction of mountain highway.
