摘　　要：介绍了第三沉降带的分布，监测得出的大量人工裂缝方向数据及由人工裂缝方向数据统计得出的最大水平主应力方向。结果表明，第三沉降带由北向南绵延1500km，最大水平主应力方向大体稳定，分布在55°～75°NE范围，多为65°NE。由监测结果可以判断，第三沉降带的构造应力方向是南亚板块及菲律宾板块共同作用的结果。Stress distribution in the third subsidence belt is presented, with great amounts of data on hydraulic fracture orientation obtained from monitoring hydraulic fracturing, and the direction of the maximum principle stress is specified. The results indicate that the third subsidence belt extends over 1 500 km from north to south, and the direction of the maximum principle stress ranges from 55°NE to 75°NE, concentrated on 65°NE, showing a stable distribution of the direction of maximum stress. The monitoring data implies that the tectonic stress direction in third subsidence belt is the combined result of South Asia Plate and Philippine Plate.
