2008年5月12日发生在龙门山断裂带上的8.0级特大地震引起了国际地球科学界的广泛关注。地震发生后,综合已有的地震地质、地球物理与形变测量资料,国内外学者提出了“刚性块体挤出”、“下地壳管道流”、“多单元组合”等多种模式解释汶川地震的力学成因。在构造应力场方面,许多学者从构造地质、地震活动、地应力测量等方面对龙门山断裂带的区域构造应力场进行了研究,获得了许多新的认识和资料,并大体上确立了人们对龙门山区
The magnitude 8.0 earthquake occurred on May 29, 2008 in the Longmen Shan fault zone has caused widespread concern in the international geoscience community. After the earthquake, based on the existing seismic geology, geophysics and deformation measurement data, scholars at home and abroad have put forward such as “rigid block extrusion”, “lower crust pipeline flow”, “multi-unit combination” and so on Various modes explain mechanics cause of Wenchuan earthquake. In the field of tectonic stress field, many scholars have studied the tectonic stress field of the Longmenshan fault zone from the aspects of tectonic geology, seismic activity and in-situ stress measurement. Many new understandings and data have been obtained, Longmen Mountain
