摘　　要：基于第五代地震动区划图,利用PyQt5设计了一款开源可视化的地震动参数计算软件。软件主要包含2个功能:①根据Ⅱ类场地基本地震动峰值加速度和加速度谱特征周期值计算其他各类场地、各级地震动峰值加速度值和加速度谱特征周期值;②根据多场点峰值加速度和场地类型进行场地调整,并对调整后的结果进行分区。该软件在地震安全性评价工作和全国地震风险普查工作的应用中有效提高了工作效率,以期为同类工作提供使用、借鉴和参考。Based on the"five generation map",an open-source visual calculation software of seismic ground motion parameters is designed by using PyQt5.The software mainly includes two functions:①Calculate all seismic ground motion parameters based on the PGA and the Tg of the basis ground motion of theⅡclass field;②Adjust the value of PGA for multiple points according to the site type,and partition the adjusted results.The software has effectively improved the work efficiency in the seismic safety evaluation and the national earthquake risk survey,and has been widely used.
