Located in the highest point of Antarctic inland, Dome A has been considered as one of the best astronomical observatory sites in the world. Some survey telescopes are planning to be installed in Dome A. Unlike any other areas, these telescopes have to be settled on the snow ground. In that case, it is very important to analyze the Snow mechanics to keep the foundation stable. The presentation firstly introduced the analysis of the snow strength in Dome A. Secondly,the dynamic and statics analysis of the telescope tower and the dome tower will be shown in this presentation. Meanwhile, some instruments has been developed to test the snow stress in Dome A by the NIAOT Antarctic team,these instruments also have been used in Beijing Winter Olympic games. |
