摘　　要：库车前陆盆地山前构造带为强挤压应力区,形成了各种复杂的推覆构造样式。利用稳定构造地区统计测井信息(电阻率、声波测井等)与最大地应力之间关系,建立并优化了估算地应力的定量数学统计模型,进而利用模型对库车山前地区地应力进行定量评价。计算结果表明稳定区的计算地应力与实验结果非常接近,山前地区计算地应力与实验结果相比较,误差水平较稳定区误差大,但仍具有较好的一致性,说明了模型的可靠性。Kuche foreland basin thrust belt is strong compressional stress zone. It comes into being various complicated overriding structural style. Using the relationship between well logging information （resistance and acoustic logging ） of regional statistics of stability structure and maximum ground stress establishes and optimizes quantitative mathematical statistical model to estimate ground stress so as to use the model to carry out quantitative evaluation for Kuche mountain front ground stress. The result shows calculated stress in stable region is approximated to that of experiment. Compared the calculated ground stress in mountain front with the experiment result, error in mountain front is more than that in stable region, but result is still consistency, which shows the reliability of the model.
