| 中文摘要: |
| 鱼山填海造地工程所处海域海况复杂，软土极为发育，而饱和软黏性土原位不排水抗剪强度是基础设计和地基处理的重要岩土指标。因此，采用电测式十字板剪切仪，并选择合适的作业平台和自主研发的船载“静”平台关键技术，极大地提高了海上十字板剪切试验的精度，解决了常规海上十字板试验指标离散性大、数据失真的问题，其技术成果为工程设计提供了有力的技术支持，也为类似工程提供借鉴。 |
| 英文摘要: |
| The sea condition of the Yushan reclamation project is complex and the soft soil is very developed. The in-situ undrained shear strength of saturated soft clay is an important geotechnical index for foundation design and foundation treatment. Therefore，the accuracy of the vane shear test is greatly improved by using the electrical vane shear instrument，selecting the appropriate operation platform and the key technology of the self-developed shipborne“static”platform，which greatly improves the accuracy of the marine vane shear test，and solves the problems of large dispersion and data distortion in the conventional offshore vane test. The technical achievements provide strong technical support for the engineering design while providing a reference for similar projects. |
