1、由於水泥假山的表麵一般不允許人、維修、清洗，也由假山公司負責，實際工程設，一般不考慮活載。在無雪地區，習慣采用垂直荷載0.5或0.60 kN/m 2來檢測假山是否會因降雨而產生水;即在此荷載作用下，水泥假山的變形輪廓線沒有近似的圓形區域。
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. 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，當低溫風速達到15 ~ 20m/s時，假山表麵幾乎沒有積雪。但如果假山表麵存在“死角”，這些部位就容易形成深雪。另外，對於一些低矢跨比的假山結構，雪的作用會導致結構表麵趨於平整，甚至在局部凹陷處，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. 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. 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.
