松花江大顶子山航电枢纽泄水闸弧形闸门封冻期应力检测

针对松花江大顶子山航电枢纽泄水闸弧形闸门数量多、冬季弧门越冬维护成本高的问题,对坝区泄水闸弧形闸门进行了封冻期闸门应力检测。通过对获得的应力数据分析,证实了冬季封冻期泄水闸弧门在直接承受江面冰载荷条件下,闸门并未产生明显变形,为大顶子山航电枢纽泄水闸无防冰措施越冬提供了数据支持。

Stress detection of water release radial gate for Songhuajiang Dadingzishan navigation-power junction

To counter the problem of the numbers and high maintenance cost of water release gate of Dadingzishan navigation-power junction in winter,we carry out stress detection on water release radial gate in the freezing period.By analyzing the stress data obtained,we confirm that the water release radial gate which bears ice load directly does not produce significant deformation.The result provides a data support for the non-measure over-winter practice of the water release gate of Dadingzishan navigation-power junction.
