摘要
为了研究高压旋喷锚索在软土地区的应用效果,选取了三组不同锚固长度和不同锚盘数量的高压旋喷锚索在软土地区进行抗拔试验,并对试验结果进行了对比分析。研究发现:高压旋喷锚索具有良好的抗拔力及抗变形性能;采用双锚盘的高压旋喷锚索与采用单锚盘的高压旋喷锚索相比,在抵抗变形能力上有显著的提升;在本次试验条件下,加长高压旋喷锚索的锚固长度对提高其抗变形能力效果并不明显。本次试验对高压旋喷锚索在软土地区工程上的推广运用具有现实的指导意义。
In order to study the application effect of high pressure jet grouting anchor cable in soft soil area, three kinds of different fixed anchor length and different number of anchor plate jet-grouting anchor were selected to carry tension experi- ment to analyze the test result in soft soil area. It was found that high pressure jet-grouting anchor cable had greatly increased the pulling resistance and anti-deformation ability. By using two anchor plates, the ability of anti-deformation has improved sig nificantly compared with using one anchor plate. Under this experimental condition, by increasing the anchor age length of high pressure jet-grouting anchor extension to improve its anti-deformation ability is not obvious. It is of great significance for the ap- plication for high pressure jet-grouting anchor in soft soil area.
