Sometimes, through the top income certificate template slopes and foothills of the slope axis will turn and bifurcation, the slope axis bending and bifurcation sites can be allowed for the construction of range restriction factors. If the building forms with orthogonal to the line as the line of control ( this is the most common case). It and the mountain slope axis may exist between straight and curved contradiction. Alleviate or avoid this kind of contradiction is the basic method, is a construction group range control in large slope axis bending between relatively flat area. Thus, the longitudinal axis of the building may be associated with mountain slope axis deviation is very small, not to break the continuity of the trend of mountain of choroid. If the building groups beyond the scope of slope axis bending parts, then the architecture group, development trend and the trend of mountain context will no longer be consistent, each other relations offensive, even building group is in slope axis bending parts for the sector, construction of longitudinal axis and the axis of the mountain slope and the relationship between still appear somewhat lacking in transition. Another possible method is to adjust the construction outline shape and trend, make it adapt to the mountain of morphological changes. With the mountain slope axis turning, thereby maintaining even further fortified mountain choroid trend. Sometimes, from the top downward slope in mountain area of central axis of a punishment of two or more than two slope axis, each have a certain direction through the foothills. In fact, the mountain slope axis bifurcation condition means a mountain is more convex, and even some mountain wing extends. For some purpose needs the help of mountain momentum building, visit mountain main context to important, mountain choroid to mainly to the convex mountain slope axis and longitudinal extending longitudinal slope of mountain Hebei axis as the mark. In the mountain slope axis forked occasions, need to judge which the slope from the top part and the axis of the slope axis with continuous, homeopathic relationship hillside site construction groups to the bifurcation of the slope axis as the constraints, there may be a mountain and the main thread of echoes, and in the imposing manner and the top parts of the building group of come down in one continuous line. For the part of construction scope, but also from the building's spatial progressive relation constraints. Buildings in the forward to the hillside site extension, but not in the longitudinal axis end parts to the hillside development.
