Dynamic Effect of the Earth Fissure Sites in the Yuncheng Basin, China

Earth fissures are widely distributed worldwide, and the Fenwei Basin in China is one of regions with most significant number scale world. The Yuncheng an important constituent basin China, where earth densely developed cause severe damage. In particular, impact on seismic response site still unknown urgent problem that needs to be solved. Based microtremor tests, three types typical fissure sites were selected for field testing. Through spectrum analysis, dynamic characteristics determined. results show significantly affected by fissures. strength largest both sides fissures, it decreases gradually stabilizes increasing distance from influence range hanging side slightly longer than heading side.
