马来西亚槟城二桥勘察新技术应用

Application of new survey technology in Penang Bridge II,Malaysia

槟城二桥是马来西亚第二座跨海大桥,地质条件复杂。勘察中大量采用拥有完全自主知识产权,具有国际竞争力的海上船载式勘探平台、钻探取样、原位测试、软土测试与中外岩土分类数据转换为一体的综合勘察新技术,解决了船载平台模块化设计、泥浆循环利用、标贯落距控制等一系列难题,为提升取土质量、减低勘察成本提供了有力的技术支撑,对我国企业跨出国门分享海外市场具有现实意义。

Penang Bridge II is the second cross-sea bridge in Malaysia with complex geological conditions.In the survey,a large number of new comprehensive survey technologies with complete independent intellectual property rights and international competitiveness have been adopted,which include the offshore ship borne exploration platform,drilling sampling,in-situ testing,soft soil testing and the transformation of Chinese and foreign geotechnical classification data,have solved a series of problems such as modular design of ship borne platform,mud recycling,standard penetration distance control,etc.It provides a strong technical support for improving the quality of soil sampling and reducing the cost of survey,which is of practical significance for Chinese enterprises to go abroad to share overseas market.
