安哥拉琼贝达拉水电站厂房基坑深且靠近河道,在项目实施中,作者从特定的地质条件分析了地下水的特点,通过试验和计算,就此制定出深基坑的管井降水方案,对管井降水技术的施工工艺和实施效果进行详述,解决了基坑降水和边坡稳定的难题,有力的保障了开挖工作的按期完成,对以后同类工程中该技术的应用有一定的借鉴意义。
In the project implementation, the author analyzed the characteristics of groundwater from the specific geological conditions. Through the experiments and calculations, the paper devised a plan of well-well dewatering for deep foundation pits, Technical construction technology and implementation effect are described in detail, which solves the problems of foundation pit dewatering and slope stability, effectively guarantees the completion of excavation on schedule, and has certain reference significance for the application of the technology in similar projects in the future.
