金川二矿区3D初始应力场的数值模拟

Numerical Simulation of 3D Initial Stress Field of Jinchuan No.2 Mining Area

金川二矿区处于复杂初始应力场中,该初始应力场由重力场和两个方向的构造应力场组成。应用ANSYS软件给出了金川二矿区复杂初始应力场的详细模拟过程,提供了一种保持应力梯度的复杂3D初应力场的模拟方法,解决了一直长期困扰分析工程师的课题。模拟方法对有关岩土工程中3D地应力场的处理有重要参考价值。

Jinchuan No. 2 mining area lies in a complex initial stress field, which is composed of gravity field and bidirectional construction stress field. ANSYS software provides a detailed simulation process for its complex initial stress field and a complex 3D simulation method for initial stress field which keeps a stress gradient, thus solving the problem which has puzzled the analyst engineers for a long time. This simulation method is of important reference value to 3D stress field treatment in geotechnical engineering.
