摘要
全新世构造应力场作用在唐山震区留下土层节理、沟槽网络系统、水系格局、地壳形变和地震破裂带等,成系列的自然现象痕迹.证明全新世以来,该区至少出现过NEE和NE向两次区域应力场的转向.唐山地震就发生在NEE向构造应力场作用的时候.
The action of holocene tectonic stress field on the Tangshan earthquake area left a series of physical traces,such as groud joints,trench network systems,drainage patterns,crust deformation and earthquake rupture zone,etc. These evidences prove that there have been at least twice deflections of the regional stress field towards the ENE and EN in this area since the Holocen epoch. It was just during the action of the tectonic stress field along the ENE that the great,Tangshan earthquake of 1976 took place.
