主 题：The Results and Comparison of Seismic Zoning in the Panxi Area Logical-Tree
摘 要：On the basis of the technological route of seismic hazard analysis,the methods for determining seismicity parameters,such as b value,annual occurrence rate,and the seismic spatial distribution function,are ***,the seismic intensity zoning in Panxi area in Southwest China is carried out by applying the logical-tree,which is made up of multi-parameter *** is clearly shown from the results that seismic intensity zoning is influenced by many uncertain factors and it is necessary to seek a certain balance between seismic safety and investment interest and a good way,with the present limited knowledge level,to obtain seismic intensity zoning is through the logical-tree method.
