摘要
针对长江水深流急的特点,考虑铺设过程中动水压力对软体排受力的影响,对系混凝土块压载体软体排在沉放过程中的受力情况进行分析。建立了采用各种铺排方式时软体排受力计算公式,并将计算结果与现场测试结果进行了对比。结果显示:理论计算与现场测量结果吻合较好,相对误差仅为4%左右。
In light of the characteristics of the Yangtze River of deep water and swift current, and under consideration of the influences of dynamic water pressure on the stress of flexible mattress during sinking, this paper analyzes the stress on flexible mattress with concrete ballast, based on which, the calculation formulae ibr the stress on flexible mattress in different ways of laying are established. The theoretical calculation result by the formulae is in good agreement with the field data, and the relative error is only around 4%.
