而骨质疏松症虽属多因子疾患，然历来文献已指出身体活动对骨骼的影响适用于任何一个年龄，其带来的承重与肌肉收缩效应通常能提供有效的外力以刺激骨形成或稳定骨量。 - According to the design theory of the cable - stayed bridge and to the feature of the cantilever construction the authors propose a construction control method called optimum completion state method ( ocsm ) for rc cable - stayed bridges in the proposed method , the optimum completion state is regarded as the final target of the construction control , and the optimum construction state at each construction stage is taken as the technical route the key of the method is to properly choose or adjust the cable forces the objectives function of optimization is to minimize the elevation error of the girder under the constraint condition that the internal forces ( bending moments ) of the girder are bounded the optimization variables are the cable forces on the basis of the above principles , a optimum model for a construction step is established and cable force adjustments can be found for each construction step in this model , the creep and shrinkage effects of concrete have been considered a bridge example is given which shows that the final state of the bridge is very close to the design aim and that this method is much better than the so - called double - control method the example is a good illustration of the soundness and practical value of the proposed method
根据现代斜拉桥结构设计理论和悬臂施工方法的特点，提出了以最佳成桥状态作为施工控制的最终目标，以实施最佳施工阶段为技术路线，以索力调整为核心内容的斜拉桥施工控制理论，简称为最佳成桥状态法；以斜拉桥主梁标高误差最小为目标函数，以主梁内力(弯矩)为约束条件，以索力为优化变量，建立了最佳施工阶段的索力调整计算模型；推导了考虑徐变收缩效应的索力调整计算公式；用最佳成桥状态法对一实桥工程进行了施工控制全过程计算研究，得到的成桥状态与设计目标相当接近，优于该桥以“双控”为控制目标的实测结果，有力地证明了本文方法的正确性及其工程实际价值
