水泥假山上的荷载及作用有哪些?

水泥假山的荷载和作用是什么?下面由假山厂家给大家介绍一下。
What is the load and function of cement rockery? The rockery manufacturer will introduce it to you.
1、由于水泥假山的表面一般是不允许掌握、保养、清洗的,也由假山公司负责实际工程设计,一般不考虑活载。在无雪地区,习惯使用0.5或0.60 kN/m 2垂直荷载来检测假山是否会因降雨而产生水;即在此荷载作用下,检查水泥假山变形后的轮廓是否存在近似的圆形区域。
1. As the surface of cement rockery is generally not allowed to master, maintain and clean, the professional rockery company is also responsible for the actual engineering design, generally without considering live load. In snow free areas, it is customary to use a vertical load of 0.5 or 0.60 kn / M 2 to detect whether the rockery will produce water due to rainfall; that is to say, under this load, check whether the contour of cement rockery after deformation has an approximate circular area.
2、在雪地里,雪对水泥假山的影响是不可忽视的。由于水泥假山大多以负高斯曲率曲面的形式出现,结构上的雪荷载一般分布不均匀;在雪荷载的计算中,应根据曲面形状和曲率的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。当假山表面的坡度大于0.4时,雪会自动滑下而不堆积。风对雪的影响也需要注意。研究表明,在低温条件下,当风速达到15 ~ 20m/s时,假山表面几乎没有积雪。但如果假山表面有一个“死角”,这些部位就容易形成较深的积雪。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,即使在局部凹陷处,也要小心处理。
2. In the snow, the impact of snow on the cement rockery can not be ignored. Because most of cement rockeries appear in the form of negative Gauss curvature surface, the snow load on the structure is generally distributed unevenly. In the calculation of snow load, the distribution of snow load should be adjusted according to the changes of surface shape and curvature, so as to consider the possible adverse effects of uneven distribution of snow load. When the slope of the rockery surface is greater than 0.4, the snow will automatically slide down without accumulating. The effect of wind on snow also needs attention. The results show that when the wind speed reaches 15-20 M / s at low temperature, there is almost no snow on the surface of the rockery. But if the rockery surface has a "dead angle", 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 structure surface to tend to be flat, even in the local depression, it should be handled carefully.

3、风的作用或按惯例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,即风载流子类型系数和风振系数。由于水泥假山体的复杂,且荷载规范中所能提供的风载流子类型系数十分有限,对于复杂的水泥硬汉类型有三种,一般国内外都是通过风洞试验方法来确定体类型系数的。预紧力的分布和大小与假山表面的形状有关,由形状的发现来决定。在内力分析中,所有的载荷组合都涉及到预紧力。
3. The action of wind or wind load according to convention is the main load in the design of cement rockery. In the calculation of wind load, two important parameters need to be determined, i.e. wind carrier type coefficient and wind vibration coefficient. Due to the complexity of the cement pseudo mountain and the limited coefficient of wind carrier type provided by the load code, there are three types of complex cement tough man, which are generally determined by wind tunnel test 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 discovery of the shape. In the internal force analysis, all load combinations involve the preload.
4. 支架和边界构件的变形会导致假山表面的应力重新分布。由于假山本身很重,地震作用的效果不是很明显。在温度变化较大的区域,应考虑热膨胀和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 the rockery itself is very heavy, the effect of earthquake action is not very obvious. In the region with large temperature change, the influence of thermal expansion and cold shrinkage on the rockwork stress and the influence of high temperature on the weld strength should be considered.
