三峡船闸地面工程开挖支护施工技术综述

三峡船闸高边坡开挖与支护是三峡工程的几大关键施工技术难题之一。在现有的施工技术水平的条件下，三峡船闸高边坡开挖与锚固这一施工技术难题，已得到较为成功的解决。对高边坡开挖支护施工技术的发展，愿意作这样一个展望：可探讨混装炸药车装药技术在高边坡开挖爆破中更大范围的推广应用，提高劳动效率；可利用现代科学技术，将高边坡开挖支护施工数字虚拟化，并将工程设计、施工和管理等信息及时反馈，使在开挖过程中的边坡岩体的完整性、稳定性和变形及其控制等可视化。

Surface Excavation and Supporting Technology for Three Gorges Shiplock

The excavation and supporting of high slopes for the Three Gorges shiplock were among the major technologically difficulties for the Three Gorges project, which have been solved successfully under current construction technological conditions. Advanced equipment of drilling and blasting, loading and hauling, as well as charging by mixing explosives truck were employed in construction. Pilot middle undercut and smooth blasting technique also were applied. Shotcreting, prestressed cables and high strength anchor bars were taken in account in the supporting. The excavation and supporting were also supported strongly by monitoring to blast vibration, displacement and stress of slope.
