本文利用韩国100多个试验点的460个地应力测量数据，分析了区域地应力场的分布规律，并提出了应力-深度和应力比-深度的相关方程。结合地质时期的古应力分析和震源机制解的应力估计，制作了朝鲜半岛半岛的地应力场韩国应力图（KSM）。通过与世界范围内的应力-深度模式的比较，证实了本文所推导的相关方程的可靠性和适用性，并通过与世界应力图的比较，估算了包括朝鲜、中国和日本在内的东北亚地区的地应力场模式。
We have analyzed the regional in-situ stress pattern using 460 stress measurement data at about 100 test sites in Korea, and suggested correlation equations of stress-depth and stress ratio-depth. We made Korea Stress Map(KSM) as in-situ stress fields of the Korean peninsula, combining with a paleo-stress analysis according to the geological period and a stress estimation from focal mechanism. We confirmed the reliability and applicability of correlation equations derived in this study, comparing with worldwide stress-depth patterns, and also estimated the pattern of in-situ stress fields of north-eastern Asia including Korea, China and Japan, comparing with World Stress Map.
