做这个动作应该有力量，但不要引起肋骨外翻或者下背部成拱形。
Vertical elements carry sufficient load through cantilever action to produce cantilever deflections equal to arch deflections.
垂直杆件则借悬臂作用产生和拱挠度相等的悬臂挠度，来承担足够的荷载。
Thermal load is one of the main loads of arch dam, at present, the method of adopting thermal load of normal concrete in RCC arch dam calculation underestimates the action of temperature.
温度荷载是拱坝最主要的荷载之一，目前，通常采用计算常态混凝土温度荷载的方法计算RCC拱坝，这低估了温降的作用。
