摘要
高压旋喷技术在地基加固和防渗止水方面有较强的适应性,均有广泛应用。在某水电站工程土石坝土质坝基防渗措施中,根据工程实际情况,进行技术经济比选处理方案,拟采用高压旋喷搭接成防渗墙的方式进行防渗。通过在坝基土层中进行不同喷射参数的旋喷试验,确定坝基地层采用高压旋喷防渗技术的可行性,并比较选择各项旋喷参数。
In seepage control project of a soil-filled dam foundation, the technical and economic comparison was carried out to select preferable countermeasure, according to the actual situation of the project. Finally we chose seepage prevention measures of high pressure jet grouting pile with cut-off wall. Through the jet grouting tests in soil layers of the dam foundation by different jet parameters, which determine that the high pressure jet grouting is feasible in impervious project of dam base, and various suitable jet parameters are presented in the paper.
