Research On Tourist Highway Landslide Hazards Landscape Treatment In Scenic Area

Treatment of scenic geological disasters were based on the conventional approach currently,without considering the particularity of scenic spots,so that treatment works on the landscape severely damaged, governance, engineering and cultural resources and natural scenic spots inconsistencies, reducing the related scenic areas of the humanities and natural value . In this paper according to the characteristics of scenic tourist highway, the scenic tourist highway distribution of geological disasters, formation mechanism, landscape-based biomimetic materials, landscape and other anti-slide pile gave a systematic study . The main results obtained are as follows:1.Chongqing Tourism scenic highway distribution, development characteristics and disaster background was analyzed. Using limit equilibrium theory and fracture mechanics studied the landslide damage crack growth mechanism.Proposed a mechanical calculation method of landslide run through.It is proved feasibility in the Three Gorges Guling landslide.The sliding zone coalescence process has been simulated by ansys. In conjunction with landslide characteristics and simulation results divided the sliding zone coalescence process into four stages:the initial stage of landslide formation,the propagation stage of sliding zone,the bulging stage of basal slope,the stage of damage. This method to the formation mechanism of landslides and landslide-depth study of effective governance laid the corresponding theoretical basis.2.For the exposed in cliffs, steep slopes and the surface lattice structure, anchor head, anti-slide pile at the top of concrete structures, to introduce two kinds of landscape biomimetic materials:landscape of concrete and the adhesive coatingmaterial.To research concrete coloring method and Surface embossing technology , analysis of landscape-type surface layer of adhesive coating material composition, coloring methods,technical requirements.Finally introduced five paint kinds of relief scenic area for tourism highway geologic hazard prevention and control structure of the coating :the antique architectural coatings, melamine paints, Imitate concrete coatings, colorful spray paint.3.According to widely used in landslide hazard for the treatment of anti-slide pile, using bionic technology, color science and landscape ecology methods, introduce landscape type of concrete and adhesive coating materials ,Carried out structural design and landscaping treatment on the exposed parts of the pile.Designed four landscapes anti-slide pile: the bionic piles, flower beds piles, pile sundial, environmental protection, anti-slide pile and to studied its design calculation methods.Carried out the design calculations of flower beds Pile in jinfoshan K9 +900 landslide.4. Analyzed the scenic geological features, climate and hydrological of Jinfoshan state-level scenic spots.Geological disasters types are summarized.To research the causes of geological disasters.Proposed governance principles of scenic area highway geologic hazard.Carried out a systematic study of the disaster landscape prevention.5.Methods for the treatment of landslide hazard theory is lagging behind the decision-making problems, analysis the fundamental factors of landslide control programs should be taked into account .Especially in scenic area tourist highway landslide control programs on the special requirements of the landscape on the Jinfoshan K9+900 landslide proposed a three kinds of landscape treatment program.Using analytic hierarchy process to establish a multi-level multi-objective optimization model of landslide ,using the fuzzy optimization theory and entropy of the right to decision-making method, to obtain the optimal landslide landscape governance program.
