摘要

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: The new airport project in Sanya planned by government of Hainan Province of China, is located at Hongtangwan of Sanya City, that is, to build an offshore airport with an area of a 28 square kilometers. The construction of this project makes great contribution to the economic development of Hainan Province, which plays an important role as a strategic fulcrum of the Maritime Silk Road. The site investigation of the land reclamation is based on the CPTU tests, which are widely used in the evaluation of characteristics of soils, but there is no related experience of offshore projects using the CPTU tests. An offshore CPTU test is carried out in the land reclamation of Sanya New Airport using the CPTU system developed by Institute of Geotechnical Engineering, Southeast University. The test results are analyzed and compared with the field data and laboratory tests. It is shown that the CPTU tests, as relatively mature in-situ tests, are applied to offshore engineering practice.
