几十来年,土质心墙堆石坝已逐渐成为世界上高坝建设的主流坝型之一,随着新型土石方机械的大量投入及填筑施工工艺水平不断提高,同时筑坝材料试验研究的深入,极大地拓宽了土石坝的用料范围和用料模式,为土石坝更广泛地应用提供了有利条件,改变了土石坝长期存在着建设工期长、填筑强度低的不足,进一步加快了施工进度,在确保填筑施工质量及安全运行的前提下探讨土石坝的快速施工是很有必要的事情。
In the coming few decades, earth core rockfill dam has gradually become one of the mainstream dam types in the world with high dam construction. With the massive investment in new type of earthwork machinery and the continuous improvement of construction technology, the experimental research on dam materials has been deepened , Which greatly broadened the range of materials and materials used by earth-rock dams, provided favorable conditions for the wider application of earth-rock dams, changed the long-term shortages of construction period and low filling strength of earth-rock dams, and further accelerated the construction It is necessary to discuss the rapid construction of earth-rock dam on the premise of ensuring the construction quality and safe operation.
