摘要
丹江口水库初期工程蓄水后,诱发地震震源浅、烈度高,对震中附近建筑物和枢纽副坝造成了不同程度的损坏。根据水库区地震地质、渗透环境条件,并结合地震活动资料,宏观预测后期水位抬升13 m后,潜在诱震区为丹库碳酸盐岩分布区的宋湾—瓦房沟及林茂山—凉水河一带,考虑到水体荷载的影响效应增加甚微,地震强度Ms<5.0级。
The source of induced earthquake is light and intensity high,varying degrees of damage is caused to the buildings in the vicinity of the epicenter and the hub of auxiliary dam.According to seismic reservoir geological and environmental conditions of penetration,combined with information on seismic activity,after macro-level elevation of 13 m,the authors forecast the potential for inducing earthquake zones are Dan reservoir carbonate distribution area of Songwan-Wafanggou and Linmaoshan-Liangshuihe area.Taking into account the impact of water load have little effect,seismic intensity Ms5.0.
