Discussion on Geotechnical Engineering problems of antenna area at QTT site
Qtai Radio Telescope(QTT),as a powerful tool for the deep space exploration by astronomers in the future,is in a syncline fold zone of the North Tianshan Mountains,which is belonging to the Cenozoic depression,with faults,folds and oth-er structures throughout the field.Due to the special engineering significance and the large construction volume of the QTT project,there are few geotechnical engineering reference cases with such weight,high pointing accuracy and high sensitivity re-quirements for the single-port telescopes domestically and abroad.Based on the particularity and complexity of geotechnical en-gineering conditions,in this paper,the potential causes,hazards and risk prevention of geotechnical engineering problems in the QTT antenna area are systematically analyzed and evaluated,and corresponding protective measures and construction points are formulated to meet the requirements of the nonuniform settlement of the large-diameter antenna foundation,and to provide theoretical basis and experience for the geotechnical engineering investigation,construction and protection of similar major sci-entific engineering facilities in the future.
