横跨1973年2月6日炉霍7.6级地震地表破裂带的虾拉沱形变场地,在该次地震后几天即投入定期流动观测。自1984年转为定点观测,先后共积累了10余年的资料。为了建设连续自记、多种形变应变观测硐,1980年在原场地(亦称下场地)顺破裂带走向的北西约500米处高约20米的台地上进行了开挖和埋桩试观测(亦称上场地),其地震地质及
The shrimp RATO deformation site spanning the surface rupture zone of the 7.6-magnitude furnace on February 6, 1973, was put into regular flow observation a few days after the earthquake. From 1984 to fixed-point observations, has accumulated a total of more than 10 years of information. In order to construct a continuous self-recording and multi-strain observation tunnel, in 1980 excavation and buried pile test were conducted on a platform about 20 meters north of the northwest about 500 meters along the rupture zone of the original site (also known as the next site) Also known as the venue), its earthquake geology and
