| 摘 要： | 国家每年都要花费大量资金用于沿海港口出海航道疏浚，而河口航道地区浮泥形成、发育和固结是直接造成航道回淤的重要原因之一。 γ－射线检测技术为观测河口、航道地区浮泥容重及分布和研究分析航道冲淤规律提供了有效手段。

| Abstract: | A lot of money is spent on dredging up navigation channels in China every year. The form, growth and consolidation of float mud in ocean outfalls and navigation channels directly leads to back silting. γ-ray gauge is a useful method for detecting the density and distribution of float mud and studying the rule of back silting. |

| Keywords: | γ-ray float mud navigation channel back silting |
