众所周知,在二向不等拉平面变形情况下,满足米赛斯屈服条件的无限平面内的圆孔周围的弹塑性应力场(k为一物理常数),早已有了精确的理论解,即加林解。其圆孔周围的弹塑性分界线为一椭圆形。但是,文献[2]直接将上述理论解答应用于满足莫尔-库仑强度准则的岩体介质中。该文说:“因为是平面应变,故σ_x+σ_y=pv+pH”(其中pv,pH是岩体的初始应力),从而得出 It is well known that in the case of unequal plane deformation in two directions, the elasto-plastic stress field (k is a physical constant) around a circular hole in an infinite plane that satisfies Mises’s yield condition has long been known to have an accurate theoretical solution. Lin solution. The elasto-plastic boundary line around the round hole is an ellipse. However, the literature [2] applies the above theoretical solution directly to rock media that satisfy the Mohr-Coulomb criterion. The article states: “Because it is plane strain, so σ_x + σ_y = pv + pH” (where pv, pH is the initial stress of the rock mass),
