目前过河索的高支柱,多采用鋼塔或鋼筋混凝土柱。但設計工作較复杂,且造价过高。为此,去年我們曾在几个水文站上試用直径102～140毫米的鋼管作低支柱,使用情况良好。今年3月底,我們又在宜阳水文站成功地架設了跨度700米、支柱高22米的吊船过河索一处。此过河索只一岸是高支柱。支柱是采用 At present, the high struts across the river, more use of steel towers or reinforced concrete columns. However, the design work is complicated and the cost is too high. For this reason, last year we had piloted steel pipes of 102 to 140 millimeters in diameter on a few hydrological stations as low-pillars and were in good condition. By the end of March this year, we succeeded in setting up a gondola across the river at 700 meters in length and 22 meters in height at Yiyang Hydrological Station. This cross-river only shore is high pillar. Pillar is adopted
