摘　　要：针对古田溪四级大坝部分坝段坝基扬压力较大的问题,应用坝基总扬压力模型和概率法对坝基扬压力性态和可能极值进行了分析,由此进一步分析了典型坝段的稳定状况。Based on the observed uplift pressure at the 4th-cascade Gutianxi dam, this paper firstly analyzes the extreme uplift pressure of the dam by the observational data model and probability. Then the stability status of the typical sections of the dam is analyzed.
