坝体削坡是土石坝工程施工中重要的工序。预留削坡余量是保证坝体坡面压实质量的一种有效施工方法。削坡余量主要视坝坡坡度、铺料厚度而定,另外也受到回填料的特性和所用施工机械性能的影响。削坡余量的预留决定坝体削坡的施工进度和质量,并最终影响工程效益。那么在坝体削坡施工中如何合理地预留削坡余量呢?笔者结合白龟山水库除险加固工程坝体削坡的实践,提出以下几点
Dam body slope cutting is an important process in earth-rock dam construction. Reserving the slope cut margin is an effective construction method to ensure the compaction quality of the dam slope. The margin of cut mainly depends on the grade of the slope and the thickness of the paving materials. In addition, it is also affected by the characteristics of the backfilling material and the mechanical properties used. The reserve for cutting slope margin determines the construction progress and quality of dam slope cutting and ultimately affects the project benefits. So how to rationally reserve the slope cut allowance in the construction of the slope cutting? In the light of the practice of Baimaishan Reservoir reinforcement and reinforcement of the dam, it puts forward the following points
