ShenZhong Passage (Island-Tunnel) Project – Refined Exploration Technology and Management

For Shen-zhong Link project with two islands and a tunnel, the survey process is in full compliance with international standards. The large-scale survey equipment with international advanced level (offshore power head drilling platform, support drilling platform) is used to carry out survey operations and tests in accordance with international standards, so as to minimize the disturbance to the undisturbed samples. Various in-situ test and indoor test methods are used to carry out all-round and multiple means for rock and soil layers. The results of the investigation are better than that of the conventional investigation and have been verified in the implementation of the island and tunnel project. Experience of this survey is helpful to promote the fine geological survey in China.
