摘要： 通过对川中公山庙构造断裂系统的成因分析认为,在挤压型构造盆地中发育的正断层是由于构造挤压力的转换,断裂“先剪后张”而形成的具有正断层效应的复合型正断层,并在地质分析的基础上,用数值分析技术和Griffith理论对其成因进行了验证,这对于挤压型盆地中的地震资料解择具有重要意义。

Abstract: The genetic analysis of faulting system in Gongshanmiao structure of middle Sidman basin show that nonnal faults in compressional basin are complex normal faults with normal fault effect. due to conversion of structural compressional stress followed by causing sheared and opened faulting，This gentic result has been verified by numerical analysis and Griffith's theory in terms of geologic analysis. It is of importance to interpretations of seismic data from compressional basins.
