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