Besides, this paper adopts the random finite element method, uses geometric and physical mechanical parameters that are relevant to lining weight of surrounding rock, coefficient of lateral pressure, height or buried depth of vertical loading, elastic resistance coefficients of surrounding rock, elastic modulus of support structure, unit weight of concrete, thickness of the structure as well as torsional strength and compression strength of concrete and etc., as random variables, applies the monte - carlo method to sampling by computer, preliminarily evaluates the reliability of bearing capacity and stability of molded concrete lining of the xuefeng mountain tunnel, and obtains the related displacement of the lining, mean value and variance of internal force, and computed the reliability index of lining structures
此外，本文採用隨機有限元方法，將圍巖容重、側壓力系數、垂直荷載高度或埋深、圍巖的彈性抗力系數、支護結構的彈性模量、混凝土容重、結構的厚度以及混凝土的抗扭與抗壓強度等與襯砌結構有關的幾何與物理力學參數作為隨機變量，應用蒙特卡洛理論進行計算機隨機取樣，對雪峰山隧道模注混凝土襯砌的承載力與穩定性的可靠度進行了初步評估，得出了襯砌的相關位移與內力的均值和方差，並計算出了相應的襯砌結構可靠指標。 -
With the increase of lateral pressure modulus, the magnitude of principal stress decreases and the direction of it is hardly changeable ; with the increase of the angle between the direction of the maximal horizontal principal stress on magnitude and the fault bearing, the magnitude of principal stress increase and its direction can hardly change ; with the increase of the elastic modulus of rocks, the magnitude of principal stress increases and the direction changes more ; with the increase of pr, the magnitude of principal stress decreases and the direction changes more ; with the increase of lateral pressure modulus, the principal stress at hance, the tress at topmost arch, bottom arch and principal stress at lateral arch decreases, with the increase of the depth of tunnel, the stress of surrounding rock also increases, and the poorer the quality of surrounding rock is, the little its principle stress is
分析得出，隨著側壓力系數的增大，主應力量值減小，主應力方位難改變；隨著與斷層走向的夾角增大，主應力量值增大，應力方向難改變：隨著巖石的彈性模量的增大，主應力量值增大，方向變化越大；隨著泊松比的增大，主應力量值減小，方位變化越大。隨著側壓力系數的增大，頂、底拱處的各應力值增大，拱腰處的主應力減小，剪應力增大，側拱處的各主應力減小，同一側壓力系數的條件下圍巖質量越差，各應力值也越小；隨著洞室埋深的增加，圍巖壓力也增大，圍巖質量越差，其應力值也減小。 -
