苏阿皮蒂大坝边坡开挖程序调整技术研究
|
摘要
针对苏阿皮蒂水利枢纽大坝坝肩边坡开挖,通过研究边坡地形地质条件及建基面开挖的设计特点,放弃了自上而下的常规开挖方式,经优化设计,在确保技术及安全措施到位的条件下,采用了自下而上的开挖程序,有效地解决了开挖工期不足的难题。
In the slope excavation of the dam abutment in Souapiti Hydropower Project,the traditional top-down excavation procedure is replaced by an optimized bottom-up procedure. The topographic and geological conditions of the slope and the design characteristics of the excavated foundation plane are analyzed. The results show that the proposed bottomup excavation procedure can greatly improve the excavation efficiency and thus solve the problem of insufficient work time limit,as long as the technical and safety measurements are good enough.
