针对所有测点测值都属于正常的大坝整体安全度评价问题,充分利用多测点信息,在假设大坝各个测点为总体的一个抽样的条件下,应用水工结构知识和Vanmarcke相关距离方法确定独立的测点群,通过各批次独立测点群及其正常工作时间获取无失效数据,在此基础上应用变形监测数据对某重力拱坝的整体安全度进行评价,工程实例证明了本方法的可行性和有效性。
針對所有測點測值都屬于正常的大壩整體安全度評價問題,充分利用多測點信息,在假設大壩各箇測點為總體的一箇抽樣的條件下,應用水工結構知識和Vanmarcke相關距離方法確定獨立的測點群,通過各批次獨立測點群及其正常工作時間穫取無失效數據,在此基礎上應用變形鑑測數據對某重力拱壩的整體安全度進行評價,工程實例證明瞭本方法的可行性和有效性。

Here ,the information of multiple monitoring points in the dam safety monitoring system was fully used to de-termine the independent monitoring point groups on the assumption that the values of monitoring points are set under the same sampling regarding to the integral safety evaluation of the dams with all regular monitoring data .In order to select the independent monitoring point groups ,Vanmarcke correlation distance method combined with hydro-structure knowl-edge were used to obtain the zero-failure data based on the independent monitoring point groups in every batch and their normal operating hours .The case study of a gravity-arch dam proves that this method is effective and practicable .
