EST（欧洲太阳望远镜）是一个4米级的太阳望远镜，目前处于概念设计阶段。EST将设在加那利群岛，目的是利用一套仪器对光球层和色球层进行高光谱、空间和时间分辨率的观测，这些仪器可以有效地产生关于等离子体在许多标度高度上的热、动力和磁特性的二维分光偏振信息。桥墩被定义为支撑望远镜和外壳的结构。它需要一定的高度来减少白天的地面颠簸。在码头的底部有一个大型仪器实验室，直径16米，高10米。码头上有一座服务大楼，容纳所有辅助服务，可能还有一座单独的大楼。实心混凝土和开放式框架桥墩进行了比较，在稳定性，热性能和流动特性和建筑结构方面的施工问题。FE和CFD分析用于定性了解替代方案之间的差异。优选的替代方案是由开放式框架包围的锥形墩。
EST (European Solar Telescope) is a 4-m class solar telescope, which is currently in the conceptual design phase. EST will be located in the Canary Islands and will aim at high spectral, spatial and temporal resolution observations in the photosphere and chromosphere, using a suite of instruments that can produce efficiently two-dimensional spectropolarimetric information of the thermal, dynamic and magnetic properties of the plasma over many scale heights. The pier is defined as the construction that supports the telescope and the enclosure. It needs a certain height to minimize daytime ground turbulence. At the bottom of the pier a large instrument lab is located, 16 m in diameter and 10 m high. To the pier is attached a service building that accommodates all auxiliary services, possibly together with a separate building. Solid concrete- and open framework piers are compared, in terms of stability, thermal properties and flow characteristics and building structures in terms of construction issues. FE and CFD analysis are used to give qualitative insight in the differences between the alternatives. The preferred alternative is a cone shaped pier surrounded by an open framework.
