Safety Evaluation On The Standaridization Embankment Project Of The Yellow River In ShanDong

The Yellow River is well known as the elevated river for its serious siltion, frequent dike breaching and channel shifting. It is much difficult to manage for frequent flood disasters. The primary task is to guarantee the safety of the yellow river from dike breaking. Presently the construction of standardizing embankment have been greatly promoted basing on the practical experience. By establishing standard safety evaluation system the function and the effects of the standard embankment can be evaluated objectively without flooding test, which plays a significant role in the construction of embankment standarization and Yellow river planning and management.The paper takes the embankmen safety influencing factor of the Yellow river in Shandong as the multitiered construction system based on the characteristic of stratification and dynamics of the embankment project.It evalues the embankment safety based on the accelerating genetic algorithm for computing rank weights in analytic hierarchy process through definiting the evaluation of the base values with the embankment safety factor investigatation and experts estatmation.By Comparing safety evaluation of the dike after and before stardarized construction in the same section, it shows that the safety ensurement degree will be greatly strengthened and enhanced, and the standardization embankement costruction improved the inner condition such as the body of dike, warping site and slope protection etc. It proves that the standardized embankment is necessary and and the results is remarkable.Meanwhile the embankment standarization didnt improve the embankment foundation, topographic condition, permeability of the dike foundation layer, leakage of the old breaking point, which need to be settled by some new technology and measures and it is the key point of dike safety.
