REVIEW AND PROSPECT ON REGIONAL CRUSTAL STABILITY OF ENGINEERING SITES

Study of the regional crustal stability of engineering sites is one of the subjects of engineering geology in China. The research history is outlined, developmental stages are divided,different opinions are introduced, new situations faced at present and future development tendencies are analysed in this paper. It indicates that selecting and evaluating relative stable landmass (called safety island) will be a basic goal for important engineering sites in the active tectonic areas.
