陕西咸阳市某厂工程场地地裂缝初步研究

通过实际观察、探井揭露和电法、浅层地震勘探等物探手段对某厂工程场地发现的地裂缝的形态、平面和竖向的延伸和分布以及裂缝中的充填物等特征进行了较深入的研究，明确了地裂缝是地下断裂在地表的反映。根据区域构造及场区历史地震的活动特征，从地裂缝发育的细微特征入手，分析、推断地裂缝的成因和时代，确定该断裂属微弱全新世活动断裂。

PRELIMINARY STUDY ON THE GROUND FISSURE IN ONE PLANT ENGINEERING SITE,SHAANXI PROVINCE

In this paper, the configuration and prolongation characteristic of ground fissure in a plant engineering site of Shanxi were gained through to actual observation, test-pitting, electrical resistivity method ad shallow layer earthquake exploration. The ground fissure is the exhibition of an underground fault on the surface. It is an weak active fault of Holocene showed by the flat surface perpendicularity's appearance, the filling, the district structure and history of earthquake.
