摘要
大地形变资料解释是一个极为复杂的问题,目前还没有用于这种解释的普遍理论和方法。本文提出和一般地讨论了大地形变资料解释中的若干基本问题。作者认为,对有关问题的广泛讨论,将有利于大地形变资料解释理论的建立和实际运用。
Using modern precise geodetic technics to detect recent crustal movement and deformation is significant to both earthquake hazard region dividing for big dam, oid pipe line, nuclear power station and other big constructions, and mineral deposition exploring. Neverthereless, the interpretation of geodetic deformation data is a very complex problem.In current references,a general series theory and method for interpretation of geodetic deformation data has not been set up yet. As the geophysics, earth interior physics, tectonophysics, experimental petrology, solid mechanics, mathematics and other related observing, laboratory and computing, technics develop, it is possible to set up a framework of the theory and method for interpretation of geodetic deformation data. This paper discusses a series of general fundamental topics, in order to set up such a framework. These topics include: 1) the representation of forward and inverse problem for interpretation of geodetic deform tion data; 2) objective and content of the interpretation of geodetic deformation data; 3) time scale, space scale and reference system for the interpretation of geodetic deformation data; 4) practical way of the interpretation of geodetic deformation data; 5) consideration of a prior information of the models for interpretation of geodetic deformation data; 6) multilayer model for interpretation of geodetic deformation data; 7) effect of lateral inhomogeneity and local boundary irregularity; 8) refining and optimizing of models for interpretation of geodetic deformation data; 9) property of the solution and practical scheme for solution of the model of geodetic deformation; 10) recognizing and evaluating of the model for interpretation of geodetic deformation data. The author thinks that the extensive discussion of these problems in this paper will be benificial to the setting up and practical applying of the theories for interpretation of geodetic deformation data.
