摘　　要：由于海洋的腐蚀环境,处于潮间带的风力发电塔对基础抗裂性要求更加严格。本文提出两种多向预应力梁板式基础的设计方案,并与现有的梁板式预应力锚栓基础进行比较。结果发现,多向预应力梁板式基础能满足更高的抗裂等级,并且能够节约钢材用量。The wind turbine generator tower in tidal zone has stricter requirements on anti-cracking ability of foundation due to the marine corrosive environment.Two design schemes of multidirectional prestressed beam-slab foundation are put forward and are compared with the existing prestressed-anchor beam-slab foundation.The results show that multidirectional prestressed beam-slab foundation satisfy higher anti-cracking level and save steel.
