海门港是历史悠久的浙中良港，６０年代以来因上游兴建大量水库堰坝，港区淤积渐趋严重。此文从地球物理角度出发，阐述了一个新颖观点，通过在台州湾北侧抛筑拦海大坝，以此减轻泥沙淤积，改善航道水深，给台州航海业参与国际竞争创造良好的硬件环境。 Haimen Port is a long-established harbor in Zhejiang Province. Since the 1960s, a large number of dam banks have been built due to the upper reaches, and siltation in the port area has become increasingly serious. In this paper, from a geophysical point of view, a novel viewpoint is elaborated. By dredging a dam on the northern side of Taizhou Bay, it can reduce siltation and water depth and create a good hardware environment for Taizhou’s maritime industry to participate in international competition .
