提升农业经济韧性是我国农业经济系统有效应对各种风险挑战的关键途径。本研究基于2011—2021年全国31个省(区、市)(不含港澳台地区)的面板数据,运用熵值法测度农业经济韧性水平,利用基准回归模型、中介效应模型、调节效应模型探究数字金融对农业经济韧性的影响及作用机制。结果表明:数字金融有助于提升农业经济韧性;数字金融覆盖广度、使用深度、数字化程度对农业经济韧性均具有显著的促进作用;不同区域数字金融对农业经济韧性的影响差异显著,其中东部地区数字金融对农业经济韧性的提升作用最大,中部和西部次之;相较于2015年之前,2016—2021年数字金融对农业经济韧性的提振作用更为显著;数字金融能够通过推动农业产业结构升级、提高农业劳动生产率和促进农业科技创新,助推农业经济韧性稳步提高;进一步研究发现,数字鸿沟和传统金融竞争在数字金融与农业经济韧性之间能够发挥调节作用。因此,应大力发展数字金融,完善数字基础设施建设,提高农户金融素养与数字技能,深化传统金融市场改革,因地制宜发挥各地区优势,充分释放数字金融对农业经济韧性的赋能作用。

Seepage and stress analysis of anti-seepage structures constructed with different concrete materials in an RCC gravity dam

引用

Water Science and Engineering 2015年第4期8卷 326-334页

作者： Ming-chao Li xin-yu guo Jonathan Shi Ze-biao Zhu State Key Laboratory of Hydraulic Engineering Simulation and Safety Tianjin University College of Engineering Louisiana State University

This study used the finite element method （FEM） to analyze the stress field and seepage field of a roller-compacted concrete （RCC） dam, with an upstream impervious layer constructed with different types of concrete materials, including three-graded RCC, two-graded RCC, conven- tional vibrated concrete （CVC）, and grout-enriched vibrated RCC （GEVR）, corresponding to the design schemes S 1 through $4. It also evaluated the anti-seepage performance of the imperious layer in the four design schemes under the normal water level and flood-check level. Stress field analysis of a retaining section and discharge section shows that the maximum tensile stress occurs near the dam heel, the maximum compressive stress occurs near the dam toe, and the stress distributions in the four schemes can satisfy the stress control criteria. Seepage field analysis shows that the uplift pressure heads in schemes S3 and S4 descend rapidly in the anti-seepage region, and that the calculated results of daily seepage flow under the steady seepage condition in these two schemes are about 30%-50% lower than those in the other two schemes, demonstrating that CVC and GEVR show better anti-seepage performance. The results provide essential parameters such as the uplift pressure head and seelga^e flow for physical model tests and anti-seepage structure selection in RCC dams.
