摘　　要：本文介绍和讨论了有关工程地震实践中的某些成果和问题：（１）考虑近源地震动饱和的衰减场模式及其转换；（２）核电厂厂址设计基准地面运动和不同核法规对人工设计时程合成的技术要求对比；（３）水利水电工程场地地震安全性评价；（４）以金沙江中下游地区为例介绍地震设防区划和设防区划图系；（５）从科学性和工程可接受性，以工程法规为基础提出工程活动断裂的定义、断裂活动性工程分类和地震断错形变工程评价。Some problemss and study results in engineering earthquake practice was discussed in the paper. They are the attenuation of relationship of near source ground motion with saturation and derivative model of near source ground motion saturation with regard to the rupture dimension of source dislocation and the attenuation field of earthquake intensities in China continent, the characteristics of design basis ground motion and the synthesis of design ground motion time history for the Nuclear Power Plant, zoning of earthquake resistance level, taking the middle lower reaches of Jinshajiang River for example, the engineering active fault, and the evaluation of surface dislocation caused by earthquake.
