关于高压旋喷锚索与普通锚索的对比试验研究

Contrast test study between high pressure jet-grouting cable and ordinary anchor cable

为了研究高压旋喷锚索在软弱土层中的应用效果,结合实际工程,选取了3根不同长度的旋喷锚索和1根足尺寸的普通锚索进行现场预应力锚索张拉试验,并对试验结果进行了对比分析。研究发现:高压旋喷锚索大大提高了锚索的抗拔力及抗变形性能。试验对该锚索在工程上的推广运用具有现实的指导意义。

In order to study the effect of high pressure jet grouting rope in soft soil layer, combining with practical engineering,we choose three different length of jet grouting cable and one full length common cable for on- site pre-stressed cable tension experiment,and analyzed the test result. We found high pressure jet grouting anchor cable had greatly increased the pulling resistance and anti-deformation property of anchor cable.
