摘　　要：中关村软件园软件广场光盘结构属车辐式双层索系,其中含径向索、斜拉索和缆风索共288根。空间索系张拉施工难点是各类索的受力相互影响,一根索内力的改变将带来其他索力的连锁变化。针对此难点对钢索张拉顺序及张拉施工模拟分析、钢索张拉的具体步骤及采用的工装设备、钢索张拉监测,进行了科学的策划,最后取得了成功。The optical disc structure at the software plaza of Zhongguancun Software Park is a spoke-like double-layer cable system composed of 288 cables, including radial cable, tensile cable and wind cable. The difficulty of tensioning construction of the space cable system lies in the interaction of cables＇ load, the variation of one cable＇s internal force causing others load to change in chain. A scientific plan was made in respects of tensioning sequence, tensioning construction simulation, detailed steps of cable tensioning and equipment to be used as well as monitoring of tensioning process, achieving a success eventually.
