| 摘 要： | 2011年以来，四川宁南汤家坪场地出现加速变化重大异常，为此中国地震局组成异常落实工作组开展现场落实，现场调查研究表明：（1）汤家坪场地观测点跨过次级断层，从破碎带中出现的石林现象，其物质组成不是第四系地层，石林陡立变形，方向性较好，与次级断裂的走向一致，应为构造岩受到挤压后变形的结果；（2）汤家坪观测场地各观测点位是... |

| Abstract: | The quick changes of fault slip in the fault-crossing deformation measurement of Tangjiaping site have appeared since 2011.A special term from several unites of CEA went to the field in order to investigate these abnormal changes.Our careful study shows following 4 possible conclusions:(1) the measurement points of site are located in both sides of sub-fault in Tangjiaping.In other words,from field investigation,the measurement site crosses a sub-fault and the geological structure around the observation sit... |
| Keywords: | Tangjiaping observation site fault-crossing measurement monitoring of short leveling and baseline measurement deformation monitoring |
