海上标准贯入试验波浪补偿技术探索
摘要:目前中外岩土勘察规范针对陆域开展标准贯入试验,均有明确而详细的使用条款。海域勘察作业时,固定在船载平台上的钻机随波浪起伏,穿心锤吊放过程受之影响,现有的勘察装备无法控制穿心锤76 cm高度的落距,使得到的标准贯入击数失真。针对海上标准贯入落锤控制方案设计、补偿模块、计算机控制等进行研究,目的使陆域成熟的SPT试验延伸至海域,满足海洋工程的需求,这对提高我国海洋工程标准贯入原位测试水平,加速海上勘察装备技术的发展具有参考价值。
Abstract:At present,there are clear and detailed terms of use for the standard penetration tests of geotechnical investechnical in China and abroad. In the sea investechnical,the drilling rig fixed on the shipboard platform is affected by the fluctuation of the wave and the process of falling hammer, the investigation equipment cannot control the distance of the 76 cm height of the falling hammer, so that the standard penetration is distorted. This paper aims at the design of the control scheme of the marine standard penetration drop hammer, the research of compensation module and computer control, which aims to extend the land SPT to sea and meet the requirements of ocean engineering,is of reference value to improve the standard of penetration in-situ test of marine engineering standards and to accelerate the development of marine reconnaissance equipment technology.
