通过对库鲁克塔格地区的构造地质演化分析,将该地区震旦系以来较强构造变形的构造应力场分4个时期:早古生代、晚古生代、中生代和新生代。根据节理、褶皱和岩墙等应力感构造的测量分析,得出库鲁克塔格地区及其周缘的4个时期构造应力场的最大主压应力方向分别为北北东向、北西西—北西向、北东向和北北东—近南北向。基于对新近纪以来库鲁克塔格地区构造应力场的二维有限元模拟,进一步对该地区应力场的分布特征、边界几何形态对应力场的影响等问题进行了讨论与分析。
Based on the analysis of tectonic and geological evolution in the Kuruktag area, tectonic stress field of strong tectonic deformation since Sinian in this area is divided into four periods: Early Paleozoic, Late Paleozoic, Mesozoic and Cenozoic. According to the measurement and analysis of the stress-sensing structures such as joints, folds and dikes, it is concluded that the maximum principal compressive stress directions of the tectonic stress field in the Kuruktag region and its periphery are respectively NNE, NWN-NWW North, East and North North East - Near North-South. Based on the two-dimensional finite element simulation of the tectonic stress field in Kuruktag area since Neogene, the distribution characteristics of stress field and the influence of boundary geometry on the stress field are discussed and analyzed.
