【摘要】：三亚新机场项目为中国海南省计划,拟于三亚市红塘湾建成的一座总面积达28平方公里的大型海上机场项目。项目的建设对于海南省发挥作为"海上丝绸之路"战略支点的重大作用,推动海南省经济高速发展具有重要意义。项目填海造岛工程的现场勘测采用海洋CPTU技术。CPTU技术作为国内外普遍使用的原位测试手段,能够有效评价土体的工程特性,但其在国内海洋工程方面仍缺乏使用经验。本文利用自主研发的CPTU设备,对三亚新机场填海造岛工程进行海上CPTU试验。结合该地区相关现场勘察及室内土工试验数据对实验结果进行分析,认为CPTU技术作为一种较为成熟的海洋原位测试技术,能够较好地应用于海洋工程实践,且具有很好的指导意义。
[Abstract]:Sanya new airport project is planned for Hainan province of China, a large sea airport project with a total area of 28 square kilometers in Hong Tang Bay, Sanya city. The construction of the project is important for Hainan province to play a major role as the strategic pivot of the "maritime Silk Road" and to promote the rapid development of the economy in Hainan province. The site survey of the project uses the marine CPTU technology.CPTU technology as a universal method of in-situ testing at home and abroad. It can effectively evaluate the engineering characteristics of the soil, but it still lacks experience in the domestic marine engineering. In this paper, the self developed CPTU equipment was used to carry out the offshore CPTU test on the sea reclamation project of the new airport in Sanya. The field investigation and laboratory geotechnical test data in this area are used to analyze the experimental results. It is considered that CPTU technology, as a more mature marine in-situ test technology, can be applied to marine engineering practice well and has good guiding significance.
