[0002] With the rapid development of domestic pumped storage power station, concrete face rockfill dam construction is increasing, dam height and scale are constantly breaking through, and higher requirements are put forward for dam foundation treatment technology. As an important part of the concrete face rockfill dam seepage prevention system, the quality of toe plate excavation and support construction is directly related to the safe and stable operation of the dam body. Due to the limitation of topographic conditions, the toe plate excavation and support of the upper reservoir project of Ziyunshan pumped storage power station in Hubei faces the difficult problem of complex toe plate excavation and support construction, mainly in the difficulties of complex topographic conditions, complex geological conditions (serious difference in weathering) and complex construction conditions. The toe plate is located in a narrow valley, with steep left and right bank abutment slopes and large topographic undulations. It has irregular geometric shape, variable cross-sectional size and complex spatial relationship. At the same time, the toe plate rock mass is broken and weathered, and there are soft interlayer or fault fracture zone, which leads to poor self-stability of surrounding rock, easy collapse, block and other geological disasters, which has great influence on construction safety. From the analysis of the existing topography and design excavation section structure of the left and right banks, the construction site of the upper reservoir is small, and large excavation and support mechanical equipment is difficult to deploy.
