| 摘 要： | 对高填方下台阶式加筋土挡墙筋带应力进行了现场实测研究分析.发现筋带上应力的分布情况分为3种,其一:筋带上全部分布着拉应力,其二:筋带上全部分布着压应力,其三:筋带上既分布着拉应力,又分布着压应力,这些和通常的加筋土挡墙所测的结果不同.究其原因主要是该实体工程的筋带为钢筋混凝土串联块,属非柔性材料,而一般加筋土挡墙的筋带为柔性材料,但是同样可以用筋带上的最大应力所在位置确定墙后填土的潜在破裂面线.

| Abstract: | The in-situ tests on the steps reinforced high earth retaining wall were carried out in order to study stresses in reinforcement.The reinforcement is R.C.series connection slab for the wall.It is found that there are three situations:① tension stresses in some reinforcements;② compressive stresses in some reinforcements;③ tensile stresses and compressive stresses in the others.It is different from that of common reinforced earth retaining wall whose reinforcement is flexible.But we can determine the location of failure line of backfill in terms of the maximum stress of reinforcement. |
