大田水库除险加固方案研究

Study of Reinforcement Schemes of Datian Reservoir

在对坝体现状渗流、稳定、应力应变分析的基础上,结合大田水库下游坝坡散浸的现场实际情况,研究并提出了适合大田水库大坝的加固方案.利用ANSYS软件的APDL语言开发三维渗流程序对坝身两种加固方案进行渗透总水头、浸润线、自由面出逸点、渗透坡降进行比较分析,最终得出最优加固方案.

On the basis of present seepage, stability, stress and strain analyses, two schemes of reinforcing Datian Reservoir are put forward according to its actual situations. The APDL language of ANSYS software is used to develop 3-D seepage programmes and compare total head lines, saturation lines, seepage gradients between two schemes. Finally, a preferred scheme is obtained.
