铜街子水电站导流明渠坝段,工程地质条件复杂。厂房坝段开挖过程中,边坡暴露出倾向河床的软弱结构面,危及明渠坝段右边墙的侧向稳定,必须加固处理。设计时曾对预应力锚固、单锚桩与钢筋拉锚等方案进行了研究。通过比较并结合施工设备现状,选用的钢筋拉锚方案,经实践考验,受荷载后运行正常。 Tongjiezi Hydropower Station Drainage Channel Dam section, the engineering geological conditions are complex. In the process of excavation in the dam section of the plant, the slope exposed the weak structural plane inclined to the river bed, endangering the lateral stability of the right wall of the Mingku dam and must be reinforced. During the design of prestressed anchors, single anchors and steel anchors and other programs were studied. By comparing and combining with the current situation of construction equipment, the selected steel pull anchor program has been tested by practice and operated normally after being loaded.
