| 摘 要： | 龙门山造山带是中国大陆的主要造山带之一，通过对龙门山中段都江堰剖面的实测研究，描述了该剖面在宏观上的构造特征，并以都江堰剖面为例对龙门山中段前山构造变形期次及应力场做了探讨。认为区域主要应力有五期，第一期NE-SW向，第二期S—N向，第三期NW—SE向，第四期铅直方向，第五期S—N向，从燕山中晚期持续到喜山期。

| Abstract: | Longmenshan orogenic belt is one of the major orogenic belts in China continent. The study of the Dujiangyan section indicates that this region underwent five-phase regional stress action such as NE-trending, longitudinal, NW-trending, vertical, and longitudinal, successively from late Yanshanian epoch to Himalayan epoch. |
