摘　　要：三峡工程分三期施工,总工期17年。三峡大坝工程混凝土量约1 610万m3,检测结果表明,大坝施工质量优良。重点对大坝各阶段蓄水前后的变形、渗流、应力应变进行了监测。分析认为,监测成果可靠合理,符合混凝土坝的一般规律,各项测值均在设计允许范围内,大坝工作性态正常。The Three Gorges Project is constructed in three phases with a total duration of 17 years.The total concrete volume of dam is about 20 million m3.Dam deformation,seepage,stress and strain before and after impounding are monitored.The monitoring results are analyzed herein and show that the results are reliable,reasonable and consistent with the general laws of concrete dam,all measured values are within the allowable design range and the construction quality of dam are good.
