| 摘 要： | 为了对某高速公路边坡的安全稳定性进行评价，在边坡上安装了12个锚杆内力测力计，根据12个月的观测数据绘出锚杆内力随时间的变化曲线，分析了降水对锚杆内力的影响、锚杆内力沿边坡高度的分布规律。得到以下两点结论：（1）由于边坡中存在软弱夹层，雨水对锚杆内力有很大的影响，锚杆内力增幅大部分在10％-20％，个别的增幅接近50％。（2）从空间上来看，锚杆内力沿边坡高度方向基本成弓形分布，下部和上部增幅较小，中部增幅较大。

| Abstract: | In order to valuate the safety of a reinforced slope of highway, 12 anchor force monitors are installed on the slope. Based on the monitoring results, it is analyzed that inelude the effect of rainfall on the change of anchor force and the rule of the change of anehor force along the slope height. The eonelusions as follows ： （ 1 ） because of rainfall in the slope, most monitoring force of anchor is increased by 10% -20% , and the maximal force is increased by 50%. （2）the anchor forces of top part and lower part of slope are less than the middle part, whieh likes a bow along the slope height. |
