| Abstract: | On the basis of the requirement of the observation piers to have the ability to work for the GNSS continuous observation in the non earthquake period and to reduce the recordable ground displacement threshold in the earthquake period, we designed and built 3 flexible GNSS observation piers with the dual drum sinking mode at Dongsanqi station. With these three flexible observation piers, we carried out the continuous observation several months in the same environment and the same time period. Through examining the results which solved in the same conditions, we have found that the flexible GNSS observation piers with the dual drum sinking mode are able to be used in the continuous observations. At the same time, the shock and pulse experiments results shown that the inverted pendulum type observation piers for testing have the amplification ability. The amplification ability of this type of piers proved the possibility to reduce the recordable ground displacement threshold. Considering that there were no earthquakes more than \%M\%3.0 in the testing area in the testing period, some more detailed study will be took out in the future. |
