［摘要］隨著城市化進(jìn)程和城市軌道交通的不斷發(fā)展，城市對(duì)快速交通系統(tǒng)覆蓋需求越來越大，車站站點(diǎn)密度需求越來越高。高架車站具有建設(shè)周期快、成本低的優(yōu)點(diǎn)，是城市軌道交通建設(shè)的重要組成部分。在地鐵線路建設(shè)過程中，部分站點(diǎn)存在因規(guī)劃等原因未能與線路同步建設(shè)，條件變化后而增設(shè)的情況。結(jié)合實(shí)際項(xiàng)目介紹了既有運(yùn)營(yíng)城市軌道交通線路增設(shè)高架車站結(jié)構(gòu)設(shè)計(jì)及保護(hù)方案，在保證了行車安全的前提下，結(jié)構(gòu)設(shè)計(jì)滿足要求，同時(shí)保證了施工進(jìn)度和質(zhì)量，獲得了較好的經(jīng)濟(jì)效益和社會(huì)效益。廣州軌道交通四號(hào)線慶盛站成為了目前全國范圍內(nèi)首個(gè)成功實(shí)現(xiàn)在既有運(yùn)營(yíng)線路上增設(shè)的高架車站，為行業(yè)提供了成功參照案例。

Abstract:With the urbanization process and the continuous development of urban rail transit, the coverage demand for rapid transit system coverage is increasing, and the demand for station density is increasing. With the advantages of fast construction cycle and low cost, elevated station is an important part of urban rail transit construction. In the process of metro line construction, some stations fail to be built synchronously with the line due to planning and other reasons, and are added after the conditions change. Combined with the actual project, the structural design scheme and protection scheme of the elevated station added to the existing urban rail transit lines were introduced. On the premise of ensuring the traffic safety, the structural design meets the requirements, while ensuring the construction progress and quality, and better economic and social benefits were obtained. Qingsheng station of Guangzhou Rail Transit Line 4 has become the first elevated station successfully added to the existing operation lines in the whole country, providing a successful reference case for the industry.

Keywords:existing rail transit; elevated station;  bridge separation; cast\|in\|place+prefabricated platform plate; uninterrrupted protection scheme
