摘　　要：结合昆明市轨道交通首期工程高架区间桥梁墩、梁外形方案设计,介绍了高架桥影响城市景观的主要因素。基于该城市景观要求,提出了适合昆明市城市特色的4种高架桥梁设计方案,并通过广泛征求意见确定山茶花方案,最后对所确定的山茶花方案的桥墩及箱梁进行了技术经济分析。分析表明,昆明市高架桥方案的桥墩在高地震烈度要求下,仍能满足节约的经济技术指标要求;而该方案箱梁技术指标相对较高,但在不考虑景观需求的前提下,其技术经济指标可达到全国其他城市同类结构的平均水平。Combining with the landscape schematic design of first stage bridge piers and bridge beams in the Kunming city,the main landscape factors of rail transit viaduct are introduced.Among the four design schemes suitable for Kunming City＇,the camellia scheme is selected as the final scheme through the public opinion poll.In addition,the technical economic analysis of pier and box-girder in the final scheme is carried out.The results show that the piers in the Kunming＇s viaduct scheme can meet the requirements of saving technical economic index in intense earthquake.The techinical index of box-girders is higher than that of other cities.Put landscape requirement aside,the technical economic index of box-girders is able to reach the national average level among similar products.
