土坝迎水坡砂壳大面积振冲加固,在国内尚属首例,开工前分别在中粗砂坝段、细砂坝段的不同高程进行了施工性试验,以确定桩距、填料量、填料方法、控制水压、留振时间等施工参数以及振冲器的配套功率。对施工中遇到的问题及时进行分析和处理,保证了施工质量,加快了施工进度。
For the first time in China, the embankment of Yingba dam and Yingxian slope sand scour and reinforce large area. Before the commencement of construction, constructional tests were carried out at different elevation of the coarse sandstone section and the fine sandstone section to determine the pile spacing, , Packing method, control of hydraulic pressure, vibration time and other construction parameters and supporting the vibration of the power device. The problems encountered in the construction of timely analysis and processing to ensure the quality of construction and speed up the construction progress.
