reclaimed water pipeline open cut trenchless pipe jacking
为实现北京地区水资源的可持续利用和水资源安全，近年来再生水利用量得到快速增加’达6．2亿m＾3／a，再生水管线建设进入高峰期。由于北京地区城市地面建筑和地下管线密集和交通流量大，传统的明挖法铺设管线存在缺乏场地且扰乱居民生活和中断交通等问题，局部支护直槽开挖及浅埋暗挖法、盾构法和顶管法等暗挖工法的优势逐渐显现，需结合地质、技术、经济及社会因素分析探讨其优缺点和适用性．从而选择最具备实施可能性的技术方案。

To achieve the sustainable use of water resources and to insure water security, the consumption of reclaimed water increases rapidly in recent years in Beijing with the annual reclaimed water use up to 6.2x10s m3. The reclaimed water pipeline construction comes into peak period. Owing to the intensive ground buildings and underground pipelines and heavy traffic in Beijing, the traditional excavation in open cut methods interrupt living and transportation and other issues. The advantage of local support straight slot excavation, the mining method, and the pipe jacking ＆ shield meth- ods gradually emergies. Based on geology, technical, economic and social factors, the superiority and applicability of a variety of ways are comprehensively analyzed, the best possible technical solution is chosen.
