Research On The Technology Of Ecological Regulation And Application About The Waterway Slope

Under the influence of a variety of natural and human factors, collapse of inlandwaterway slope is a common natural phenomenon. At present, the natural orecological construction concept are more and more focused on in the waterwayengineering.As to slope Ecological Engineering,it is still in the initial stage. Perfectdesign technology, the project evaluation theory,the simulation tecology, slopestability analysis based on multi-factor about slope ecological improvement, and othercore issues rarely were researched. The problems Above-mentioned are researched inthe thesis, tclearly stated the definition and connotation of the waterway ecologicalmanagement he main contents and conclusions are as follows:(1) The definition and connotation of the waterway slope ecologicalimprovement were firstly proved. The design techniques of ecological improvmentabout the waterway slope such as slope design principles and design parameters.andtwo new waterway ecological revetment structure was developed;The evaluationtheory about ecological slope engineering, involved in each index group in evaluationindex system, the evaluation model established by analytic hierarchy process.(2)The strength test was done about undisturbed clay included grass-roots,remodeling clay included grass-roots and remodeling the prime soil, and comparisonof test results showed: main influencing factors of soil strength are the distributionpattern of grass-roots and root content. With confining pressure increases, the rooteffect of improving soil strength gradually stabilized, showing certain boundaryeffects. Soil strength influenced by the grass-roots show―the best root content‖. Withthe root content increases, cohesive force increases when the root content is less thanthe best root content of soil. With the root content increases, cohesion reduces whenthe root content is more than the best root content of soil. Internal friction angle doesnot reflect the significant variation. The undisturbed clay included grass-roots is muchhigher than the reinforcing effect of the remodeling clay included grass-roots, and thelaw of the same strength between the undisturbed clay included grass-roots andremodeling clay included grass-roots with multiple grass-roots is found. Both for theeffect of sample cohesion contribution quite, When the root content of remodelingclay included grass-roots is about that of undisturbed clay included grass-roots of2.6 times.(3) Strength reduction FEM was for the method of slope stability analysisDetermined by theoretical analysis, a finite element analysis model is established byABAQUS process, and the simulation of the various factors of the slope wasexplained. the model was verified by the measured data to meet the studyrequirements. Finally, the slope failure failure criterion was provided.(4) The inland waterways soil and ecological slope stability were analysisedbased on the single factor and multi-factor combinations, the situations andmechanism of destruction of slope destruction based on different factors andcombinations were provided, Plant slope reinforcement effect and its mechanism wereshowned by the slope ecological improvement before and after. Studies suggest thatthe most influential factor on the waterways slope stability is lowering the waterlevels, the second is rainfall, the third is steady seepage, and finally is the ship waves.(5) According to the results of the study in the paper, slope of the demonstrationproject is designed based on the ecological improvement, before and after theengineering of the ecological improvement of waterway slope stability wasanalysised.then the slope of the engineering after ecological improvement wasevaluated, The results showed that engineering meet the requirements of theecological improved of waterway slope.
