土坝原型观测的目的,一是监测坝在运用中的安全,二是研究坝在各种外力及自然因素影响下的变化规律,为科研和坝工技术的发展提供有用资料。观测设备应视具体情况针对上述目的布设,以期达到预想的效果。为此,本文对土坝外部观测的布设提出几点粗浅意见。一、坝身渗透测压管的布设目前大多数土坝的坝身渗透观测,习惯称为浸润线观测。其布置一般有两种典型方式:一是主要布设在代表性断面(如最大坝高处,合拢段)上以测量坝身浸润线(坝内渗流水面线),并与设计浸润
The purpose of earth dam prototype observation is to monitor the safety of dams in operation and to study the variation rules of dams under the influence of various external forces and natural factors so as to provide useful information for the development of research and dam technology. Observation equipment should be arranged for the above purposes, as appropriate, in order to achieve the desired effect. For this reason, this article puts forward some superficial opinions on the layout of earth dam external observation. First, the dam body penetration piezometric pipe layout At present, most of the earth dam dam penetration observation, accustomed to the so-called wetting line observations. There are generally two kinds of typical arrangements: First, the main layout in the representative sections (such as the maximum height of the dam, close section) to measure the dam infiltration line (dam seepage water line), and the design infiltration
