| 摘 要： | 对于渗流问题,特别是地下岩体中的渗流,由于条件复杂随机性,具有不确定性。结合区间分析基本理论,给出了裂隙网络渗流区间控制方程。并结合算例利用Monte-Carlo区间分析方法对层状裂隙隙宽为区间变量的流场进行了渗流分析。

| Abstract: | It is uncertain for seepage analysis,especially for underground rock seepage problem,because of complex and random conditions.According to basic principle of interval analysis,control equations of seepage interval for fracture network are proposed.Using Monte-Carlo interval analysis method,seepage in flow field of layer fracture with variable fracture width in a interval is calculated and analyzed. |
