Yangtze river tunnel project in Wuhan is the first tunnel through Yangtze river in China,high technical require-ment for geotechnical engineering investigation is necessary,but its construction is difficult. Conventional survey methods are difficult to solve positioning of water drilling and testing difficulties on Yangtze river,low core recovery percentage of sand,special geotechnical parameters indicators testing such as thermal property,groundwater flow rate and flow on Yan-gtze river testing problems,and so on. therefore by adopting many anchors combination positioning,dynamic tracking cor-rection technology,isotope tracer method testing groundwater flow velocity and direction,exploration depth monitoring technology,rotary cutting type drilling technology of sand satisfactorily solve the geotechnical engineering investigation problems and provide accurate geotechnical engineering data for the wuhan Yangtze river tunnel project construction.
