黄龙带水库大坝安全监测自动化总体设计

General design of automatic safety monitoring system for Huanglongdai dam

黄龙带水库大坝的自动化监测项目包括坝基水平位移、垂直位移与转动监测、坝身及坝基的渗漏量监测、气温与坝温监测、库水位监测及基础渗压监测等。众多的自动化仪器与数据自动采集与管理软件系统构成了一个较为典型的比较全面的自动化监测系统，是国内大坝安全监测中自动化程度最高的监测系统之一。坝基水平位移自动化监测系统布置在１２１ｍ高程廊道中，通过埋设在１２１ｍ高程基础廊道里的遥测垂线坐标仪进行量测，垂直位移自动化监测系统布置在１２７ｍ高程廊道内，以遥测静力水准仪测各沉陷点的相对沉陷、各种监测仪器布局合理，该系统的总体设计和监测原理具有一定的先进性，对其它大坝的安全监测有一定的借鉴作用。

The automatic monitoring items for Huanglongdai dam include the horizontal and vertical displacements and rotational motion of the dam base,seepages in dam body and foundation,the air temperature,the dam temperature, the reservoir level,the seepage pressure in foundation, and others. A large number of automatic monitoring apparatuses and data acquisition and management software systems form a comparatively typical and complete automatic monitoring system which is one of monitoring systems of the highest level in automatization in China. The automatic monitoring system for the horizontal displacement of the dam base is placed in 121 in elevation gallery,and the horizontal displacements are measured by means of the remote measuring coordinatographs which are placed in the same gallery. The automatic monitoring system for vertical displacements of the dam base is placed in the 127 m elevation gallery,and the relative settlement at every point is measured by means of the remote measuring static leveler. The arrangement of various apparatuses is reasonable. The general design and monitoring principle of this system are quite advanced,which may be for other project's reference.
