摘要

介绍了永胜6.0级地震震区的自然概貌,将影响震害的四种主要场地条件按其影响轻重分类,用震害指数划分了该次地震的震害分布及局部异常区,分析了局部场地特征对震害的影响。结果表明:在影响震害的诸多场地条件中,场地土特性的影响较显著,地形的影响不明显,场地土、覆盖层和地下水的影响有互相制约的现象。
Natural situation in the earthquake area of the M6.0 Yongsheng earthquake is presented in the paper. Classifying of four site conditions influencing earthquake disaster according to their influence to earthquake disaster is made. The distribution of the earthquake disaster and the anomalous area of the earthquake are divided by means of disaster index. The results show that foundation soil has obvious influence to the earthquake disaster. And the foundation soil, overburden and groundwater level influencing the earthquake disaster have phenomena restricting each other.
