| A great many of slopes are excavated owing to infrasture constructions, e.g. highway, railway, water and electricity engineering, mine exploitation, the excavation destroys the original vegetation and leads to a lot of naked land and serious soil loss. Consequently, the ecology balance is broken up. Slope eco-protection technology, regarded as an important way to restore and protect the damaged environment, has been widely applied. thus it is necessary to further the related theory and the engineering research.Eco-protection on rocky slope is difficult to be realized for its own ecological characteristics. Recently a new kind of protection technology, e.g. spraying growing basis material, which can be applied to high and steep rocky slope has been invented in China, and the development of growing basis material is the main subject. This thesis, aiming to improve the rocky slope ecological technology, chose growing basis material as research object and some studies were done through experiments.(1) The suitable materials were chosen for each component to combine a new type of growing basis material though characteristic test and analysis of function of each component, the components included soil, organic fertilizer, water, cement, improver, water retaining material, slowing releasing fertilizer, pH buffering dose and seeds.(2) Taking plant's growth condition, compressive strength of growing basis material and its shrinkage and drought combating ability as the judging targets, several uncertain but maybe important materials, i.e. organic fertilizer, cement, improver, water retaining material as the influencing factors, an orthogonal experiment was designed to combine the experimental specimens, which provided a scientific and reasonable method to choose growing basis material.(3) Though the tests, the results of each target were obtained. By max-min difference and variance analysis, the remarkably influencing factors of each judging target were finded out.(4) The rules and trends of index varing with obvivous factors were attained. Moreover, the reasonable range of each component quantities was concluded by the comprehensive balancing method. |
