浙江省萧山围垦二十三工段垦区占地面积60km~2,新建干堤12km,该工段面对钱塘江入海口,属涌潮冲击强度最大、流速最快的地段之一。实测潮水水流速度11m/s,涌浪冲击强度7t/m~2,涌潮高度为2.5m,潮差8m左右。此段险工、险段时有发生。以往采用传统抛块石,钢筋笼、4t异形块体组成工坝、挑流等工程措施及 Zhejiang Xiaoshan Reclamation Twenty-three section reclamation area covers an area of ​​60km ~ 2, the new dry embankment 12km, the section facing the Qiantang estuary, a tidal surge impact strength of the fastest, one of the fastest flow. The measured tidal current velocity is 11m / s, surge impact intensity is 7t / m ~ 2, tidal height is 2.5m, tidal range is about 8m. This section of insurance workers, insurance period has occurred. In the past, the traditional throwing stone, steel cage, 4t shaped blocks form dam, pick flow and other engineering measures and
