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。
The new airport project in Sanya is a large-scale maritime airport project planned by Hainan Province of China to be completed in Hongtangwan, Sanya City, with a total area of 28 square kilometers. The construction of the project is of great significance to Hainan Province as a major strategic pillar of “the Silk Road on the Sea” and to promote the rapid economic development of Hainan Province. The site reclamation and islanding project site survey using marine CPTU technology. CPTU technology, as a commonly used in-situ test method at home and abroad, can effectively evaluate the engineering characteristics of soils. However, CPTU technology still lacks experience in domestic offshore engineering. In this paper, using self-developed CPTU equipment, marine reclamation project of Sanya new airport offshore CPTU test. Based on the relevant site survey and indoor geotechnical test data in this area, the experimental results are analyzed. CPTU technology is considered as a more mature in situ testing technology and can be applied to ocean engineering practice well and has good guiding significance.
