生物聚合物加筋土堤坝稳定性评估的试验研究

Experimental Study on Stability Assessment of Biopolymer Reinforced Earth Dam

水泥和其他类似的化合物已被用于防止洪水期间的堤坝决口,为提高堤坝的耐久性和环保性,采用了一种新型环保材料生物聚合物制作堤坝模型,并进行了水工模型试验,评估新堤坝的可靠性和稳定性,并应用图像分析来计算堤坝斜坡的破坏范围。文章根据试验结果,比较了土堤与拟建堤坝之间的破口特征,并根据不同厚度的新型物质来评价堤体的稳定性。本研究的最终目的是通过在一系列水工试验中验证新物质在堤坝破坏因素方面的性能和有效性,得出最佳条件。

Cement and other similar compounds have been used to prevent dam breaches during floods.In order to improve the durability and environmental protection of the dam,biopolymer,a kind of new environmental protection material is used to make the dam model.A hydraulic model test is carried out to evaluate the reliability and stability of the dam,and image analysis is applied to calculate the failure range of dam slope.According to the experimental results,the breach characteristics of both the earth dam and the proposed dam are compared,and the stability of the dam is evaluated according to the new material with different thicknesses.The ultimate purpose of this paper is to verify the performance and effectiveness of the new material in terms of the failure factors of the dam through a series of hydraulic experiments,and to obtain the best conditions.
