Abstract: In order to solve the problem of stability and seepage caused by complicated geological conditions at the left bank of Juxianmiao reservoir, scheme of attaching slope type auxiliary dam at the left bank is put forward based on site investigation of the topography and geological conditions. By pouring certain thickness of concrete as a control panel upstream and setting the anchor to make mountain on the left bank and the anti-seepage panel as a whole, scheme of attaching slope type auxiliary dam makes full use of the mountain on the left bank. It is verified by experiment that this scheme not only solves the stability and seepage problems on the left bank, but also saves engineering quantity and investment. It is worthy of reference for similar projects.

Key words: Juxianmiao reservoir, attaching slope type auxiliary dam, stalibity, seepage prevention

摘要: 为解决聚仙庙水库因左岸地质条件复杂且稳定性较差而引起的坝体稳定和防渗问题,在对地形及地质岩性进一步分析的基础上,提出了左岸“贴坡式副坝”的设计方案。工程充分利用左岸山体,在其上游面护砌一定厚度的混凝土作为防渗面板,将左坝肩较为单薄的山体全面包围,并设锚杆将左岸山体及其防渗面板连成一个整体,作为左岸的“贴坡式副坝”。经试验验证,这种设计既解决了左岸的稳定和防渗问题,又节省了筑坝工程量和工程投资。“贴坡式副坝”设计方案可为重力坝及类似的工程设计提供借鉴和参考。
