文章以丰富的资料论述了大渡河流域的新构造运动与活断层,提出:大渡河流域的新构造运动是断块式的差异运动,各断块以不同的速率升降,断块间的边界断层则是差异活动集中的场所。边界断层就其活动时代,可分为老断层、新断层和活断层。活断层与国民经济建设关系密切,就其活动方式可分为错动型和蠕动型:断层错动,发生强震,对工程危害极大。文章以水电工程为目标,给出了评价断块和活断层稳定性的标准。
The paper discusses the neotectonic movement and active fault in Dadu River basin with rich data. It is proposed that the new tectonic movement of Dadu River basin is block-like differential movement, each fault block goes up and down at different rates, and boundary fault between fault blocks It is the place of difference activities. The boundary faults can be divided into old faults, new faults and active faults in their active era. The active fault is closely related to the construction of the national economy. The active fault can be divided into two types: the fault type and the peristaltic type. The fault faults and strong earthquakes occur and are extremely harmful to the project. In this paper, the hydropower project as the goal, given the evaluation of fault block and active fault stability standards.
