In this paper, experiments and their results in SHUIBUYA project responding to its features and the designed requirements are introduced, and main blasting parameters of DIA and TTTR are proposed.

Rapid construction technology for extra-long highway tunnel with drilling and exploding method;

By the analysis of engineering character about weathered trough of benthic highway tunnel traversing the Xiamen East Passage Channel and successful examples of drilling and exploding methods at home and abroad,the time of advanced grout reinforcement and the scope of construction techniques for traversing weathered trough are confirmed in virtue of numerical simulation method.

Taking the value simulation conclusion as the basis of construction plan and through computation,the geometric shape and the drill and blast plan of the partial excavation were determined.
