摘要
本文对天马和谢坊试验场的三角和基线观测资料进行了应变分析,获得了该试验场的主应变值、主应变方向以及剪应变值。分析结果表明,该试验场的地壳形变特征基本上是由通过该场地的断层所制约,反映了该断层的性质。
In the paper, the data of base and trigonometric observations at Tianma and Xiefang experiment site are analysed. The principal strain and its azimuth and the shear strain are calculated. The analysis results show that the character of crustal deformation at two sites principally are constrained by faults which pass through these sites. The crustal deformation basically reflected the behaviour of these faults.
