随着时代的发展,我国水利工程建设行业处于快速发展状态中,水利工程的建设管理逐步完善。橡胶坝是水利工程建设中一个重要的技术,通常也叫做橡胶水闸,主要是运用了高强度的合成纤维,这些纤维织物发挥了较强的承载作用。运行橡胶纤维,对水利工程项目内外进行涂抹,这就可以作为项目的保护膜,可以实现按照坝高来控制上游水位,它是保证水利工程又好又快可持续发展的基础,并且方便了国民的生活。接下来笔者将结合自己多年从事水利工程建设的经验和调查走访结果,基于橡胶坝施工技术的内容特点,详细论述水利工程建设中橡胶坝施工技术的应用。 相似文献

在水利工程中,橡胶坝也称之为橡胶水闸,通常在高强度合成纤维织物中发挥着受力骨架的作用,采用橡胶对其内外进行涂敷,作为保护层进行使用。能够按照坝高的调节来促使上游水未得到控制,从而使橡胶坝发电、灌溉、防洪、航运以及挡潮的效果得到充分发挥。 相似文献

The Environment Agency has accepted the need for public participation in decisions concerning river management in keeping with Agenda 21 concerns for environmental policies that command a good measure of public support. In the past, public participation has often relied upon consultations involving formal meetings with interest groups and local politicians. Methods of public consultation are changing. In tapping public opinion the Environment Agency now relies less on public meetings and increasingly more on a direct approach and involvement of the public. Research at Middlesex University is part of the attempt to provide opportunities for the representation of views of the lay public to be considered within the management of rivers and river corridors. The research has used surveys of representative samples of members of the public, often at riverside sites. This paper reports on some of the research projects that have developed on these themes, and analyses the implications of their results for river management and the protection of nature conservation values. 相似文献

A new model for predicting the frequency of extreme river levels is proposed which encapsulates physical knowledge about river dynamics. The central idea is the use of continuous time stochastic processes that use hydrological equations and ergodic theory to model extreme events, rather than relying on statistical fits of classical models to local maximum data. A simple example shows how changes in discharge characteristics change the extreme river level frequencies. Solutions are provided for special cases, and directions for more general techniques are provided. 相似文献

Water samples were collected weekly from the Tovdal river at Boen in southern Norway over the period August 1978–December 1979, and were analysed for pH, sulphate, chloride, nitrate, sodium, potassium, calcium, magnesium, ammonium, aluminium, dissolved silica and weak and strong acids. During the 16 month study period, the river pH showed a much smaller than normal seasonal variation, ranging from a maximum of 5.14 to a minimum of 4.64. The general pattern of the variation in the concentration of both the atmosphere-derived species (sulphate, nitrate and ammonium) and the ground-derived alkalis (calcium, magnesium and potassium) was a steady increase during the autumn and winter to a broad peak during the spring, followed by a minimum concentration during the summer. Nitrate and ammonium exhibited some differences from this pattern since they are rapidly metabolized. The peak in the concentration of sulphate and nitrate which occurred in the spring of 1979 was matched by an equivalent increase in the alkalis leached from the ground, indicating that ground interactions were rapid during the snow-melt period. In the autumn of 1979, the sulphate concentration increased to values higher than in the previous autumn, and, since the concentrations of the leached alkalis did not increase by an equivalent amount, the pH decreased.The seasonal variation in the measured weak acid concentration also exhibited a late winter/spring maximum and a summer minimum. The measured weak acid concentration is shown to have the theoretical dependence on the aluminium, silica and ammonium concentrations together with a dependence on the total organic carbon concentration. For data from the Langtjern catchment, this dependence was found to be 2.3 μeq mgC−1, and, with a value of 4.75 μeq mgC−1, the theoretical relationship satisfactorily fitted the weak acid data from the Tovdal in the spring of 1977, and was also consistent with the measurements from the present study. The seasonal variation in the measured weak acid content was largely explained by the variation in the concentration of the inorganic weak acid species. 相似文献
