Analysis Of Damming The Red Clay Of Evolution

Our teachers made pursuant to this topic and get to the widely recognized on the carbonate rocks overlying the red clay to form a new model based on research emphasis on the meso-clay dam in Yunnan Plateau evolution of the law is expected to raise red clay dam at the library in the evolution of water environment mechanism for the dam material selection,zoning and size distribution,screening provide a theoretical basis.Broad application prospects of this topic. China is the world's largest number of earth-rock dam,due to historical reasons,the overall poor quality of these dams,for example,1973-1974,the dam-break rate was 18%. Earth-rock dam in China to date is still mostly risky project,a direct threat to their hidden lives and property of the people,in particular,restricted the agricultural production process of modernization. China's Ministry of Water Resources organized experts to conduct large-scale survey results show that the domestic more than 90% of the earth-rock dam seepage varying degrees of disease,in which the proportion of urgent treatment for more than 70%. To this end, state and local governments raised a huge sum of money every year to reinforce the implementation of the dam in 2007 alone permitted to repair the dam in Yunnan Province reached more than 200 seats,invested more than 800 million yuan. Reinforcement of the embankment dam seepage at home and abroad to take measures in the seepage control study to compare the selection process,never considering the composition of Earth Dam Materials degradation trends in the evolution of Meso, resulting in impervious reinforced embankment dam or unit investment is too high, or impervious body life is too short,the overall efficiency are generally low.As a basic research project,technical route to the scene and a lot of data analysis, research-based,and the corresponding crystalline materials,the evolution of chemical experiments and observations,ultimately the security of dangerous reservoirs in Yunnan identification of data validation results of the scientific. The results obtained for the plateau of Yunnan clay used in the traditional earth-rock dam seepage over the years reinforced the applicability of technology to provide practical guidance to evaluate and improve the program,and to use other primary materials of the earth-rock dam seepage study on the dam seepage control technology complete reference.
