吊杆式 meaning in Chinese
derrick type
Examples
- As a brand new supporting structure , the steeve - arch was firstly used in the design of tangyu aqueduct ( also used as a bridge ) lies on the eastern main ditch of shitou river , shaanxi province
吊杆式拱架作为一种新型拱式支承结构在陕西省石头河东干渠汤峪渡槽(桥渡结合工程)设计中首创应用。 - 3 , the comparing analyses of tech - economic features , anti - seismic features on transverse direction of the aqueduct 1 ) from the angle of engineering cost , steeve - arch supporting structure , whose down beam have tectonic cracks , can spend less money up to 90 % or more than the usual arch supporting structure , namely steeve - arch supporting structure is very obvious on the side of cost
3 、技术经济比较分析1 )从造价方面看，下弦杆分缝的吊杆式拱架结构相对于下弦杆构造不分缝的竖杆式拱架结构可节约工程造价达到90以上，吊杆拱的经济效果十分明显。 - 2 ) from the angle of constructing course , steeve - arch supporting structure requires low - capacity cranes to erect , and simple constructing methods easy to meet . the time spending on construction is short . the usual arch supporting structure requires high - capacity cranes to erect , and complicate constructing methods hard to meet
2 )从施工角度看，吊杆式拱架支承结构对吊车的起吊能力要求低，工艺简单，施工方便，工期短；竖杆式拱架支承结构起顶重量大，对吊车的起吊能力要求高，施工难度大。 - 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
本文试图就上述的这两大方面的内容，从以下三个角度进行了初步研究： 1 、纵槽向抗震性能分析1 )汤峪河吊杆拱支承结构的纵槽向地震效应较小；吊杆式拱架结构动力特性取决于槽墩和主拱圈的刚度，以及结构的整体性，故适当加大构件截面尺寸或提高砼标号，尽量降低结构的建筑高度和重心，在构件连接和变截面处增设梗胁，按照约束混凝土的要求来加强箍筋的配置，增加砼的延性，以克服地震时构件连接和变截面处的应力集中造成的坡坏，并吸收大量的地震能量，从而起到隔震，减震的效果。
