| 摘 要： | 地下岩体天然裂缝的发育受多种因素控制，发育机理非常复杂，且裂缝不能直接观察。依据裂缝分布的数值模拟步骤，通过观察、描术岩心的裂缝发育特征，分析在发育过程中裂缝发育的控制因素及其对岩体力学性质的影响，建立裂缝发育概率计算的数学模型，进而对裂缝发育概率分布和发育特点做出了预测，根据实例计算结果，探讨了裂缝分布对地下流体活动的控制作用。

| Abstract: | The developing of underground stratum fracture,with very complicated mechanism,is invisible and controlled by many fcators.According to the steps of fracture numerical simulation,by observing and describing the fracture characteristics of cores,the controlling factors of cracking and its influence on rock mechanical property are analyzed,the mathematic model for fracture developing proability calculating is constructed.Moreover,the distribution of fracture developing probability and developing characters are predicted.Based on the calculating results of a sample,the controlling of underground liquid movement by fracture distribution is discussed,and some conclusions are given. |
