lateral arch meaning in English
侧向拱
Examples
- 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，随着侧压力系数的增大，主应力量值减小，主应力方位难改变；随着与断层走向的夹角增大，主应力量值增大，应力方向难改变：随着岩石的弹性模量的增大，主应力量值增大，方向变化越大；随着泊松比的增大，主应力量值减小，方位变化越大。随着侧压力系数的增大，顶、底拱处的各应力值增大，拱腰处的主应力减小，剪应力增大，侧拱处的各主应力减小，同一侧压力系数的条件下围岩质量越差，各应力值也越小；随着洞室埋深的增加，围岩压力也增大，围岩质量越差，其应力值也减小。
