摘　　要：援柬埔寨国家体育场屋盖采用斜拉索桁结构,针对全柔性鱼腹式索桁架与斜拉索相结合的技术特点,采用低空胎架拼装、斜拉索整体提升、下径向索分步张拉的施工技术。通过采用分段螺杆式节点,有效承受了环索节点处的不平衡力。对施工过程监测方法与监测内容进行研究,保障拉索施工阶段结构安全与质量。The roof of Cambodia National Stadium adopts the inclined cable truss structure.According to the technical characteristics of the combination of the fully flexible fish-belly cable truss and the inclined cable,the construction technology based on the assembly of the low-altitude tire frame,the overall lifting of the inclined cable,and the step-by-step tension of the lower radial cable is adopted.By adopting segmented screw joints,the unbalanced force at the ring-cable joints can be effectively supported.The monitoring method and monitoring content of the construction process are studied to ensure the structural safety and quality of the cable during the construction stage.
