摘　　要：城市地下通道装配式铺盖法基于基坑支护系统,采用装配式铺盖板(包含便于后期浇筑的人孔浇筑井、限制铺盖板位移的限位装置)及其上部的路面结构层作为临时路面。该方法具有缓解地面道路交通压力、加快施工速度、减小工程造价等优势。结合工程实例,介绍了在交通繁忙、场地狭小、地下管线复杂等施工条件下可采用装配式铺盖法进行下穿通道施工,并对施工关键技术要点进行了总结。The urban underground laying assembly coverplate method based on a pit support system,to adopt the assembly coverplate(includes pouring well and limiters)and their upper pavement structure layer as a temporary pavement.This method has the advantages of alleviating the pressure of traffic,accelerating the construction speed and reducing cost.This paper combines examples of engineering,introducing this method can be used the working condition such as heavy traffic,small sites and complex underground pipelines.And summarize the key technical points of construction.
