摘要

苏阿皮蒂枢纽大坝最大坝高120 m,针对坝基钻孔涌水对多点位移计埋设安装质量和观测数据精度的严重影响,通过优化施工工艺,增设排水管、控制灌浆压力、调整浆液配合比的综合处理措施,成功埋设安装多点位移计29套,取得了大量精准的观测数据,为判断大坝坝基变形稳定性提供了可靠的依据。
        Since the maximum height of the Souaptiti dam is 120 m,water gushing from the boreholes in the dam foundation will seriously affect the embedment installation quality of the multipoint extensometers and the observation accuracy. A series of comprehensive treatment measures are proposed to optimize the installation process,including adding the drainage pipes,controlling the grouting pressure and adjusting the grouting mixture ratio. With these measures,29 sets of multipoint extensometers are successfully installed and accurate observation data are obtained,which provides a reliable basis for the judgement of the dam foundation deformation and stability.
