摘　　要：分析了混凝土等级为C30、C25、C20、C15情况下的五种不同厚度的混凝土衬砌板边坡稳定的影响;混凝土板的厚度分别取为10cm、15cm、20cm、25cm和30cm。相同混凝土板厚下,边坡稳定安全系数随着混凝土等级的增大而增大;相同混凝土等级下,边坡稳定安全系数随着混凝土板厚的增大而增大;边坡稳定安全系数随着混凝土板厚和等级的增加,变化趋势逐渐变缓,从而得出混凝土板对渠道边坡稳定具有保护作用。Analysis of five different thickness of the concrete board liner on the stability of the tunnel slope in the concrete grade C30、C25、C20、C15 with concrete board thickness are 10cm、15cm、20cm、25cm and 30cm separately were carried out.safety factor is increase along with the concrete grade in the same concrete board thickness;Safety factor of slope is increase with concrete thickness in the same concrete board grade;Change trend of safety factor of slope gently turn smooth with concrete thickness and grade＇ increase,then concrete board had function of protection on the stability of the tunnel slope.
