四川活动断裂研究的进展及其在工程场地地震安全性评价中的作用

The Development of Research on Active Faults in Sichuan Province and Its Function on Seismic Safty Evaluation at Engineering Fields

四川地处青藏高原的东南缘，近代地壳运动强烈，活断裂发育，强震频繁。本文总结了四川活动断裂研究从定性向定量的发展．在此基础之上讨论了活动断裂研究在国民经济建设中的作用。

Sichuan is situated at the southeastern bounder of Qingtzang plateau, there are strong ofrecent crust movement. Many kinds of active faults and frequent of strong earthquakes occursin the region. The research developments of active fault are concluded and then the functionsof active fault research in economic construction are discussed.
