以汤峪河渡槽为例，对新型吊杆式拱架结构的内力特性进行了全面分析。结果表明，该结构与下承式桁架拱比较，具有内力分布均匀且控制性内力显著减小，无需采用预应力措施，更便于采用分块吊装拼接工艺施工；是密实砂卵石基或岩基上修建大跨度渡槽的一种经济实用的新型模式。 Taking the Tanghe River aqueduct as an example, the internal force characteristics of the new boom-type arch structure were comprehensively analyzed. The results show that compared with the trussed arches, the structure has uniform internal force distribution and significantly reduced internal forces of control. No prestressing measures are needed, and it is more convenient to use the block lifting and splicing process; it is compacted sand pebble base or rock foundation. A new economical and practical model for building large-span aqueducts.
