| 中文摘要:对青藏高原昆仑山和羊八井的地应力实测结果表明，昆仑山的最大水平主应力量值为6.8-12.9MPa；羊八井的最大水平主应力值为3.3-10.4MPa，总体来看，昆仑山的应力值比羊八井高。与中国其他地区表层地应力测量结果比较，从区域应力分析角度来看是属于高应力区。它们的最大主应力方向与NE和NEE。这与青藏高原大陆动力学研究的结论是一致的。此外，结合工程地质调查结果，对青藏铁路昆仑山隧道和羊八井隧道群的有关问题进行了讨论。 |

| Recent Ground Stress Measurement of the Kunlun Mountains and Yangbajing Area in Qinghai-Tibet Plateau and Its Engineering Significance |

| Abstract:This paper reports the ground stress measurements of the Kunlun Mountains and Yangbajing area in Qinghai Tibet plateau. The result indicates that maximum horizontal principal stresses are 6.8～12.9 MPa near the surface of Kunlun Mountains, and 3.3～10.4 MPa in Yanbajing. The stress values of the Kunlun Mountains is higher than those of Yangbajing, and they are of high values as compared with those obtained elsewhere in China from a viewpoint of regional stress analysis. The maximum principal stresses are in NE and NEE directions. This agrees with the result of the study of continent dynamics. Combined with engineering geological condition, this paper discusses some related problems about the Kunlunshan tunnel and the Yangbajing tunnel along the Qinghai Tibet Railway under construction. |
