复杂地质条件下高土石坝渗流控制与防渗结构优化设计研究OA

In view of complex geological conditions,high earth-rock dams are faced with complex seepage field distribution and high potential seepage damage risks.This paper selects typical projects such as Jinping Level 1,Xiaowan and Longtan as research objects,and adopts on-site monitoring,numerical simulation and optimization design.The combination of methods analyzes the impact of geological heterogeneity on the seepage field of the dam body,and constructs a collaborative optimization design system for impervious walls and core walls.The research results show that Comprehensive control measures can greatly reduce seepage flow and improve the overall safety factor of the dam body,providing scientific support for the design and long-term operation of the anti-seepage system of high earth-rock dams.
