摘要
拉西瓦水电站位于高地应力区,为减少坝基开挖后的卸荷回弹,结合实际地质情况,通过对坝基开挖施工工艺的研究、探索,总结出一套有针对性的施工方法及施工工艺,有效地解决了高地应力区的坝基开挖问题,避免了坝基开挖的二次处理,加快了施工进度,提高了经济效益,可供类似工程地基开挖参考。
Laxiwa Hydropower Station is situated on an area with high terrestrial stress. In order to reduce unloaded elasticity after the excavation of dam foundation, in combination with the actual geological conditions and based on the research and exploration of excavation of dam foundation, a set of effective construction method and construction techniques were summarized, which solves effectively dam foundation excavation in the region with high terrestrial stress, avoids secondary treatment of dam foundation excavation, accelerates the progress of construction and increases economic benefits.
