摘要
本文通过对坝基渗流观测资料的整理与分析,揭示了扬压力和渗流量的变化规律,以及坝前淤积对扬压值的影响关系。指出加强排水是降低渗透压力和解决扬压值陡升的根本途径。
Through processing and analysis of the observed data of seepage flow thro ugh the darn foundation, this paper reveals the regularities of variation of the uplift pressure and the quantity of seepage flow and the effect of siltation in front of the dam on the value of uplift pressure, and points out that drainage is a fundamental way to reduce the seepage pressure and to prevent the value of uplift pressure from abrupt rise.
