沥青混凝土心墙坝位错计和测斜管安装埋设方法的探讨

Installation and embedding method of dislocation gauge and inclinometer tube in an asphalt con⁃crete core dam

适合的安装埋设方法是监测仪器埋设成活率的保障。沥青混凝土心墙坝监测仪器的安装埋设不同于其他材料的大坝。笔者介绍了某水库沥青混凝土心墙坝的施工特点,分析总结了位错计和测斜管常规安装埋设方法中存在的问题,结合现场施工情况,提出了适用于沥青混凝土心墙坝的改进安装埋设方法,取得了良好的应用效果,可供类似工程参考。

Suitable installation and embedding method is the guarantee of high survival rate of monitor⁃ing instruments.The installation of safety monitoring instruments for asphalt concrete core dams is differ⁃ent from that of other dam types.This paper introduces the construction characteristics of the asphalt concrete core dam of a reservoir and the problems existing in the conventional installation and embed⁃ding of dislocation gauge and inclinometer tube are analyzed and summarized.Based on the field con⁃struction,an improved installation and embedding method for asphalt concrete core dam is put forward which is effective and worth reference for similar projects.
