第三章采用大涡模拟亚格子涡粘模型，对岩滩混流式水轮机的流场进行三维非定常湍流分析，得到了流场中各物理量的脉动特性，计算出ms的轴向水推力与模型试验值大小相当；同时论证了对于下机架承重的混流式水轮发电机组可采用其推力轴承负荷作为水电站厂房振动的最大垂直激振荷载。 - For getting the runner characteristics more correctly , researching the representation of runner characteristics of the kaplan turbine in this paper , and using this method of modifying runner characteristics to calculate the transient of hydraulic power station . improving the calculating model of the axial thrust in the kaplan turbine ' s transient . base on the theory of screw propeller without any boundary , using the theory of screw propeller with pipe , and the formula to calculate the dynamic axial thrust during transient is developed
本文对转桨机组在过渡过程中的桨叶划水产生水推力的数学模型进行了改进，在原来使用无边界螺旋桨进行等效的基础上，使用了导管螺旋桨对转桨机组中的桨叶划水进行等效，并且比较详细的分析了影响转桨机组轴向水推力的各个因素，以及给出了动态计算轴向水推力的公式，通过计算表明，使用改进后的动态水推力计算模型得到的结果能较好的反应实测的动态轴向水推力。 - With the further economic growth and the implement of development of the western regions , hydroelectric construction in our country is undergoing rapid growth , anumber of high - dam power - station is in building or in programming . in view of its higher - head and larger magnitude of spill structure outlet , it is difficult for conventional concrete or reinforced concrete structure of pier and pier room to support its vast water pressure . coupled with the improvement of prestressed method , it has been the noteworthy tool in solving the problem
随着我国经济的加速发展及西部大开发战略的实施，我国水电事业也迎来了迅猛发展的大好时机，一批高坝水电站正在建设或规划之中，其泄水建筑物孔口及水头愈来愈大，常规混凝土或钢筋混凝土闸室闸墩结构难以承受如此之大的水推力作用，随着预应力技术的成熟，这一技术已成为解决该问题的关键技术措施之一。
