例句與用法

  1. 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(cè)壓力系數(shù)的增大,主應(yīng)力量值減小,主應(yīng)力方位難改變;隨著與斷層走向的夾角增大,主應(yīng)力量值增大,應(yīng)力方向難改變:隨著巖石的彈性模量的增大,主應(yīng)力量值增大,方向變化越大;隨著泊松比的增大,主應(yīng)力量值減小,方位變化越大。隨著側(cè)壓力系數(shù)的增大,頂、底拱處的各應(yīng)力值增大,拱腰處的主應(yīng)力減小,剪應(yīng)力增大,側(cè)拱處的各主應(yīng)力減小,同一側(cè)壓力系數(shù)的條件下圍巖質(zhì)量越差,各應(yīng)力值也越小;隨著洞室埋深的增加,圍巖壓力也增大,圍巖質(zhì)量越差,其應(yīng)力值也減小。
