摘要將起重量和起吊幅度為基本設計依據，以壓桿穩定理論為分析基礎，結合專業知識，建立物理模型，解決了起重量、起吊幅度與吊臂質量、吊臂主要參數之間的函數關系的難題，首次確定出設計參數的自然邊界條件，為起重機設計者提供了確定設計參數的新方法和科學依據，具有開創意義。On the contents of two sides abovementined, this paper attempts to do some initial researches from three angles as follows : 1, the analyses of anti - seismic features on longitudinal direction of the aqueduct l ) the seismic longitudinal effects are small. the vibrant characters are decided from the structure integration and rigidness of piers and main arch - ring of the aqueduct, so the following measures should be taken in order to weaken and isolate seismic influence : properly broadening the section sizes and adopting the high class concrete, lowering the height and barycenter of building, setting hoop steel bars so as to increase the plasticity of the concrete which can absorb the seismic energy and prevent the damages due to stress centralization on the linkages and changing place
本文試圖就上述的這兩大方面的內容，從以下三個角度進行了初步研究： 1 、縱槽向抗震性能分析1 ）湯峪河吊桿拱支承結構的縱槽向地震效應較小；吊桿式拱架結構動力特性取決于槽墩和主拱圈的剛度，以及結構的整體性，故適當加大構件截面尺寸或提高砼標號，盡量降低結構的建築高度和重心，在構件連接和變截面處增設梗脅，按照約束混凝土的要求來加強箍筋的配置，增加砼的延性，以克服地震時構件連接和變截面處的應力集中造成的坡壞，並吸收大量的地震能量，從而起到隔震，減震的效果。Specification for derrick boom clamp
