水泥假山上的荷载及作用有哪些?

水泥假山上的荷载及作用有哪些呢?下面就由济南假山制作给大家介绍一下。
What are the loads and functions of cement rockery? The following is about the rockery in Jinan.
1、由于水泥假山表面一般不允许上人,检修、清洗也是由假山公司负责,实际工程设计中,一般不考虑活荷载。在非降雪地区,习惯上用 0.5 或 0.60 kN/m 2 的竖向荷载来检测假山是否会因降雨而产生积水;即检查在此荷载作用下,变形后水泥假山的等高线有无近似的圆形区域出现。
1. Due to the fact that people are not allowed to go on the surface of cement rockery, the professional rockery company is also responsible for the maintenance and cleaning. In the actual engineering design, the live load is generally not considered. In non snowfall area, it is customary to use the vertical load of 0.5 or 0.60 kn / m2 to detect whether the rockery will generate ponding due to rainfall; that is to check whether the contour line of the deformed cement rockery has an approximate circular area under the action of this load.
2、在降雪地区,积雪对水泥假山的影响是不容忽视的。由于水泥假山多呈负高斯曲率曲面形式,结构上的雪荷载一般为非均匀分布;在计算雪荷载时需根据不同曲面形状、曲率变化来调整雪荷载的分布,以考虑雪荷载不均匀分布可能产生的不利影响。当假山面坡度大于 0.4 时,落雪一般会自动滑下而不产生堆积。风对积雪形式的影响也需要加以注意。研究表明,低温条件下当风速达到 15~20m/s 时,假山面几乎不存在积雪;但如果假山面存在“死角”则在这些部位极易形成较深的积雪。另外,对于某些低矢跨比的假山结构,积雪的作用会导致结构表面趋于平坦,甚至在局部出现下凹,必须小心对待。

2. In the snow area, the influence of snow on cement rockery can not be ignored. Because cement rockery is mostly in the form of negative Gaussian curvature surface, the snow load on the structure is generally non-uniform distribution; when calculating the snow load, it is necessary to adjust the distribution of snow load according to different surface shape and curvature changes, so as to consider the possible adverse effects of uneven distribution of snow load. When the slope of rockery surface is greater than 0.4, the falling snow will automatically slide down without accumulation. The effect of wind on the form of snow also needs attention. The results show that there is almost no snow cover on the rockery when the wind speed reaches 15-20m / s at low temperature; however, if there is "dead angle" on the rockery surface, it is easy to form deep snow in these parts. In addition, for some rockery structures with low rise span ratio, the effect of snow will lead to flat structure surface, and even local concave, which must be treated carefully.
3、风作用或者按习惯说法风荷载是水泥假山设计中的主要荷载。在计算风荷载时需要确定两个重要的参数,即风载体型系数和风振系数。由于水泥假山的体型复杂,而各国荷载规范所能提供的风载体型系数又十分有限,对复杂体型的水泥家伙三,国内外一般都通过风洞试验的方法来确定体型系数。预张力的分布及大小与假山面的形状有关,由找形确定。在作内力分析时,预张力参与所有荷载组合。
3. The main wind load in cement is wind load. In the calculation of wind load, it is necessary to determine two important parameters, i.e. wind load shape coefficient and wind vibration coefficient. As the shape of cement rockery is complex, and the shape coefficient of wind load provided by load codes of various countries is very limited, the shape coefficient of cement rockery with complex shape is generally determined by wind tunnel test at home and abroad. The distribution and size of pretension are related to the shape of rockery surface and determined by shape finding. In internal force analysis, pretension is involved in all load combinations.
4、支承及边界构件的变形会导致假山面应力重分布。由于假山本身的质量很重,地震作用的影响不是很明显。在温度变化大的地区,还要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 the supporting and boundary components will lead to the redistribution of stress on the rockery surface. Because the rockery itself is very heavy, the effect of earthquake is not very obvious. In the area with large temperature change, the influence of thermal expansion and cold contraction on the stress of rockery and the influence of high temperature on weld strength should be considered.
