上海地震台阵是中国大陆第一个自行设计和建设的三分向、宽频带、大动态、永久性的地震台阵,距离上海东海岸线约65 km。上海市位于长江入海口,属于冲积平原,覆盖层的平均厚度300 m,部分地区超过450 m,全市仅在金山、松江地区有十余处火山岩组成的小山丘。上海地震台阵为依东、西佘山而建的准规则小尺度台阵,由l6个子台组成,孔径约为3 km,子台的间距约为600 m,海拔高度10 m,在地表以下2 m处的安山岩上直接开凿摆墩然后再建摆房。子台地理
The Shanghai Seismic Array is the first three-point, broadband, large-dynamic and permanent seismic array designed and constructed in mainland China, about 65 km away from the east coast of Shanghai. Located in the estuary of the Yangtze River, Shanghai belongs to the alluvial plain. The average thickness of the overburden is 300 m. In some areas, it is over 450 m. There are more than ten volcanic rocks in Jinshan and Songjiang areas. The quasi-rule small-scale array of the Seismic Array of Shanghai, based on the east and west Sheshan, consists of l6 sub-stations with a pore diameter of about 3 km and a sub-station spacing of about 600 m and an altitude of 10 m below the surface An mound at the m rock directly on the pier and then build the house.
