水泥假山上的荷载及作用有哪些呢?

  1、由于水泥假山的表面一般不允许人、维修、清洗,也由假山公司负责,实际工程设,一般不考虑活载。在无雪地区,习惯采用垂直荷载0.5或0.60 kN/m 2来检测假山是否会因降雨而产生水;即在此荷载作用下,水泥假山的变形轮廓线没有近似的圆形区域。
  1. As the surface of cement rockery is generally not allowed to be repaired, cleaned, and also in the charge of a professional rockery company, live load is generally not considered in the actual engineering design. In the snow free area, it is customary to use the vertical load of 0.5 or 0.60 kn / M 2 to detect whether the rockery will produce water due to rainfall; that is, under this load, the deformation contour of the cement rockery has no approximate circular area.
  2、在降雪地区,雪对水泥假山的影响不容忽视。由于水泥假山多为负高斯曲率曲面形式,结构上的雪荷载一般分布不均匀;在计算雪荷载时,应根据不同的曲面形状和曲率变化来调整雪荷载的分布,以考虑雪荷载分布不均匀可能带来的不利影响。当假山表面坡度大于0.4时,落雪一般会自动滑下而无堆积。风对积雪模式的影响也需要注意。
  2. In snowy areas, the impact of snow on cement rockery can not be ignored. Because the cement rockery is mostly in the form of negative Gauss curvature surface, the snow load on the structure is generally distributed unevenly. When calculating the snow load, the distribution of snow load should be adjusted according to the different surface shape and curvature changes, so as to consider the possible adverse effects caused by the uneven distribution of snow load. When the slope of the rockery surface is greater than 0.4, the falling snow will automatically slide down without accumulation. The effect of wind on snow pattern should also be noted.
  研究表明,当低温风速达到15 ~ 20m/s时,假山表面几乎没有积雪。但如果假山表面存在“死角”,这些部位就容易形成深雪。另外,对于一些低矢跨比的假山结构,雪的作用会导致结构表面趋于平整,甚至在局部凹陷处,一定要小心。

  The results show that when the low temperature wind speed reaches 15-20 M / s, there is almost no snow on the surface of the rockery. But if there is a "dead angle" on the surface of the rockery, these parts are easy to form deep snow. In addition, for some rockery structures with low rise to span ratio, the effect of snow will cause the surface of the structure to tend to be flat, even in local depressions, we must be careful.
  3、风作用或按自定义风荷载是水泥假山设计中的主要荷载。西安假山在计算风荷载时需要确定两个重要的参数,即风载系数和风振系数。由于水泥假山的形状复杂,而各国的荷载规范所能提供的风载流子类型系数十分有限,对复杂形状的水泥盖伊三、国内外一般通过风洞试验方法来确定形状系数。预紧力的分布和大小与假山表面的形状有关,这是由找形决定的。在内力分析中,预应力参与所有的荷载组合。
  3. Wind action or according to custom wind load is the main load in the design of cement rockery. Two important parameters, wind load coefficient and wind vibration coefficient, need to be determined when calculating wind load of Xi'an rockery. Because the shape of cement rockery is complex, and the wind carrier type coefficient provided by the load codes of various countries is very limited, the shape coefficient is generally determined by the wind tunnel test method for the complex shape of cement Gai 3 and at home and abroad. The distribution and magnitude of the preload are related to the shape of the rockery surface, which is determined by the shape finding. In the analysis of internal force, prestress participates in all load combinations.
  4、支架和边界构件的变形会导致假山表面应力重新分布。由于假山本身质量很重,地震作用的影响不是很明显。在温度变化较大的区域,应考虑热胀冷缩对假山应力的影响以及高温对焊缝强度的影响。
  4. The deformation of supports and boundary components will lead to the redistribution of stress on the surface of rockery. Because of the heavy quality of the rockery itself, the influence of earthquake action is not obvious. In the region with large temperature change, the influence of thermal expansion and contraction on the rockwork stress and the influence of high temperature on the weld strength should be considered.
