水工防渗帷幕方案论证及后评价技术
|
摘要
水工防渗帷幕作为大型"地下挡水建筑物",通常因建设条件隐蔽、技术复杂、造价高昂而构成工程兴建的关键要素或决策焦点,制约工程成败。以一大型防渗帷幕工程论证为载体,阐述了坐落于复杂岩溶暗河背景下的防渗方案论证、优化比选、节点路径等关键技术,并探讨了地下幕体施工质量的"后评价"技术。纵观该工程从前期论证、实施到运行的全过程,均已做到了精心、精准和精确到位(可靠性),取得了全面的成功,具有一定的推广应用价值,可为我国其他同类工程提供参考和借鉴。
As a large underground water-blocking structure,anti-seepage curtain is usually very crucial to the success of a hydraulic project,because its enshrouded construction condition,complex techniques,high cost of construction.Based on a large-scale project of anti-seepage curtain located in a complicate karst condition,the author mainly expounds the key techniques of the plan demonstration,optimizing comparison,node path,and also the post-evaluation of the underground curtain construction quality.Throughout the project,from feasibility study,construction work to the final function phase,nothing but accurate and precise work was done,which contributed to a total success.The results have certain application value,and can be for reference of other similar projects.
