构皮滩水电站缆机基础设计与施工

Design and construction of cable crane foundation of Goupitan Hydropower Station

构皮滩水电站大坝混凝土选用中速、无塔式、缆索式起重机浇筑,其基础具有承受荷载大,动荷载不断变化的特点。在缆机基础结构设计过程中,充分考虑荷载、地形地质、施工场地、施工手段等因素,选择了合理结构形式;在缆机基础施工过程中,针对所遇到的地质问题,结合原有设计方案和现场机械设备,采用了经济易行的处理方法。

In the construction of Goupitan Hydropower Station, the medium speed, no - tower, cable type crane is applied in concrete pouring. The bearing load of its foundation is large and the dynamic load changes constantly. In the design of foundation structure of cable crane, the factors including load, topographic geologic, construction field and construction method are considered and the reasonable structure type is selected ; in the construction of crane foundation, combing with original design scheme and insitu mechanical equipment, we used economical and convenient method to overcome the faced geological problems.
