| 摘要: |
| 随着海洋开发事业的发展,海底钢铁设施日益增多,但这些设施均不同程度地受到了海底泥的腐蚀,而目前世界上对海底泥腐蚀性研究的报道不多,更无钢铁在海底泥中的腐蚀数据。国外曾对海泥的腐蚀性进行过因子分析(Roger,1980),但由于方法问题未解决而使研究未能深入。
海底泥和陆地土壤相同之处是两者都是泥沙石组成的不均匀体系,不同的是陆地土是由固、液、气三相组成的多项体系,而海底泥只有固、液两相组成。
本试验借助地质取样器,在不破坏土壤结构的情况下将其移植岸边进行埋片,再放回大海中,参与原海洋体系的循环,对钢在海底泥中腐蚀进行定量研究,这种海土腐蚀实验方法作者称之为“MD”海底泥腐蚀试验法(试验海土取自辽东湾9.84-41.4m深层海底)。 |

| Abstract: |
| In this marine engineering geological investigation, 5 kinds of sea-bottom soils in the Liaodong Bay were studied using new angly techniques, a marine engineering geological examination vessel and our patented technology developed for testing “MD"corrosion test pipe in the seabottom soil. The corrosion rates of 3 kinds of steel are given, and the steel corrosion mechanism and its relation to environmental factors are discussed. |
