| 中文摘要: |
| 本文总结了钱塘江强潮河段修建丁坝的实践经验，对丁坝坝轴方向、坝长、坝距、坝顶高程及坝身断面抵御强潮的作用和参数的合理选择等均作了分析。根据两个地段修建丁坝的实践认为采用密距短丁坝群促淤护塘的效果显著。通过分析对比建坝前后的实测资料，说明了这一方法的效果，是解决海塘基础防冲，提高海塘整体稳定性的一项行之有效的工程措施。 |
| 英文摘要: |
| The practice experience of groin building against the strong tide in Qiantang Estuary is persented. The effects of groin direction, length, space, elevation and cross section of the dam on tide resistance are analyzed an d the principles for adopting the relevant parameters are proposed. It is concluded that to arrange the short low groins in groups is the best scheme for enhancing the tide resistance and preventing the erosion of groins and seawalls. The effectiveness of this technology is verified by observation data. |
